General Description
The MAX14870/MAX14872 motor drivers provide a small,
low-power and simple solution for driving and controlling
brushed DC motors and relays with voltages between
4.5V and 36V. Very low driver on-resistance reduces
power dissipation.
These drivers feature a charge-pump-less design for
reduced external components and low supply current.
Integrated fast-decay current regulation allows user-
adjustable peak startup motor currents and requires mini-
mal external components.
A separate voltage-sense input (SNS) reduces current
sensing errors due to parasitic trace resistance.
The MAX14870/MAX14872 features shoot-through protec-
tion and internal free-wheeling diodes that absorb inductive
motor currents. Driver outputs are short-circuit-protected
from shorts to ground, to the supply, and between M1 and
M2. An active-low FAULT output signals thermal overload
and overcurrents during fault conditions.
The MAX14870 has PWM and direction-control inputs,
while the MAX14872 has forward and reverse inputs for
direction control. See the Function Tables.
The MAX14870/MAX14872 are available in a 12-pin
(3mm x 3mm) TDFN-EP package and operate over the
-40°C to +85°C temperature range.

Functional Diagrams
Detailed Description
The MAX14870/MAX14872 DC brushed motor drivers
provide a low-power and flexible solution for driving and
controlling brushed motors with voltages between 4.5V
and 36V. Peak motor currents of up to 2.5A ensure large
motor torque that is controllable by an external PWM
signal and/or by autonomous internal current regulation.
The MAX14870 has PWM and direction-control inputs,
while the MAX14872 has forward and reverse inputs for
direction control. See the MAX14870 Function Table and
MAX14872 Function Table.
Charge-pump-less design requires minimal external
components and low supply current.
Integrated current regulation allows limiting peak start-
up motor currents. Shoot-through protection with a
140ns (typ) dead time ensures low operating current.
Internal free-wheeling diodes absorb inductive motor cur-
rents. The FAULT output signals thermal overload and
overcurrents.
Overcurrent Protection
The MAX14870/MAX14872 are protected against shorts
on M1/M2 to any voltage between VDD and GND, includ-
ing shorts to GND, VDD, and between M1 and M2 via
overcurrent limiting. When a current above 6A (typ)
flows through M1 or M2 for longer than 1µs, an overcur-
rent condition is detected and the H-bridge drivers are
automatically disabled and the FAULT output asserts.
If the overcurrent condition continues for longer than the
overcurrent autoretry timeout (2ms (typ)) the MAX14870/
MAX14872 enters autoretry mode. In autoretry mode,
the M1 and M2 outputs are re-enabled for 1µs (typ) and
FAULT goes high-impedance. The drivers are disabled
again and FAULT is re-asserted if the overcurrent condi-
tion persists.
PWM Control (MAX14870 Only)
The PWM input is used for motor speed/torque control.
Increasing or decreasing the duty cycle at PWM sets the
effective (average) voltage across the motor terminals
and allows first-order speed control.
When PWM is logic-high, the motor is driven in the direc-
tion defined by DIR. When PWM is logic-low, the bridge
is in brake mode. In brake mode, the motor current
continues flowing and recirculates through the low-side
transistors of the H-bridge driver, due to its inductive
impedance and back EMF.
FWD/REV Control (MAX14872 only)
The FWD input is used to drive the motor forward/turn a
relay on. The REV input reverses the M1 and M2 polarity,
to drive the motor in reverse/turn a relay off.
FWD/REV control can be optionally used to implement
either bipolar motor control (with both M1 and M2 switch-
ing) or unipolar control, where only M1 or M2 switches.
Slope Control
The MAX14871 drivers turn-on and turn-off with active
slope-control during the M1/M2 transition times. The
integrated slew rate-limiting reduces EMC (like conducted
and radiated EMI) associated with high di/dt rates.
Thermal Shutdown
The MAX14870/MAX14872 include integrated protection
against thermal overload. When the junction temperature
exceeds 160°C (typ), the H-bridge is three-stated, M1 and
M2 are disabled, and FAULT is asserted.
If the motor was spinning before thermal shutdown
occurred, the motor’s inductance will push current through
the internal M1 and M2 diodes, forcing the motor into fast
decay, with a voltage across its terminals of VDD.
M1 and M2 are automatically reenabled when the
junction temperature falls to 150°C (typ).
Current Sensing
Connect a sense resistor (RSENSE) between COM
and GND to monitor the motor current during operation.
Select RSENSE such that the voltage at COM created by
motor current flowing through the sense resistor is limited
to within 250mV relative to GND (-250mV ≤ VCOM ≤
+250mV).
Minimize series trace resistance from RSENSE to GND
to minimize voltage sense errors due to parasitic trace
interconnect resistance. Use a star ground connection
between the MAX14870/MAX14872 GND pins and the
GND-side of RSENSE. Connect the voltage sense close
to the RSENSE resistor and/or use differential voltage
sensing. See Figure 4.

Current Regulation
The MAX14870/MAX14872 features internal current
regulation to limit the startup current. Regulation is set
when the motor current (IM) exceeds the current limit
defined by the sense resistor (RSENSE):
IM_MAX = 0.1V/RSENSE
When the motor current exceeds the maximum threshold,
the H-bridge drive is reversed for fast decay for a fixed
time (tOFF = 15μs). The H-bridge is turned back to normal
operation after tOFF.
Fast Decay Mode
When the motor current exceeds the set threshold, the
H-bridge polarity is reversed during the 15μs (typ) tOFF
period. This results in faster motor current decay since
–VDD is applied across the motor’s terminals. The motor
current decrease is first order with an L/R time constant
and proportional to (VDD + VEMF).
Note that if tOFF is larger than the motor’s L/R electrical
time constant, the motor current can reverse direction,
causing the motor to not start.
During fast decay, the motor’s inductive current recircu-
lates through the external VDD supply, which charges up
the VDD bypass capacitor. Therefore, the voltage seen
across RSENSE is negative during the tOFF delay.
Applications Information
Layout Considerations
Connect duplicate pins (COM pins and VDD pins) togeth-
er with low-resistance traces. See the Current Sensing
section for further layout recommendations.
Power Considerations
The MAX14870/MAX14872 driver can generate more
power than the package for the device can safely dissi-
pate. Total power dissipation for the device is calculated
using the following equation:
PTOTAL = PDRIVER + PSW + PD
The power dissipated inside of the driver is calculated as:
PDRIVER = IM2 x RON

where IM is the motor current and RON is the on-resis-
tance of the high and low-side FETs.
PSW is the power generated by the driver during the rise/
fall times in switching and includes both arms of the bridge.
Calculate PSW using the following equation:
PSW = IM x 2 x VDS
= IM x 2 x (1/2 x VDD x fSW x tR)
where IM is the motor current, tR is the 200ns (typ) rise
or fall time of the driver output, and fSW is the switching
frequency.
The internal diodes dissipate power during switching, as
well. Calculate the power dissipated in the diodes as:
PD = IM x 2 x VBF x tDEAD x fSW
Operation Without Current Regulation
To operate the MAX14870/MAX14872 without internal or
external current regulation, connect SNS directly to GND.
No sense resistor is required for this configuration.
Operation with External Current Regulation
The motor current can be controlled by external PWM
regulation using sense resistor feedback in a control loop.
To disable the internal current regulation circuitry of the
MAX14870/MAX14872 and use external regulation, con-
nect SNS directly to ground.
Note that, if fast decay control is used, the COM voltage
pulses negatively when the H-bridge direction is inverted.
Use of External Capacitors
Maxim does not recommend using external capacitors
across the motor terminals. Added capacitance between
H-bridge outputs increases the power dissipated in the
H-bridge by:
PD = VDD2 x C x fSW
where C is the capacitance across M1/M2 and fSW is
the M1/M2 switching frequency. This power is dissipated
without good reason.
