description
The TPIC0298 is a dual high-current full-H driver
designed to provide bidirectional drive currents of
up to 2 A at voltages from 5 V to 46 V . It is designed
to drive inductive loads such as relays, solenoids,
dc motors, stepping motors, and other high-
current or high-voltage loads in positive-supply
applications. All inputs are TTL compatible. Each
output (Y) is a complete totem-pole drive with a
Darlington transistor sink and a pseudo-
Darlington source. Each full-H driver is enabled
separately. Outputs 1Y1 and 1Y2 are enabled by
1EN and outputs 2Y1 and 2Y2 are enabled by
2EN. When an EN input is high, the associated
channels are active. When an EN input is low , the
associated channels are off (i.e., in the high-
impedance state).
Each half of the device forms a full-H reversible
driver suitable for solenoid or motor applications.
The current in each full-H driver can be monitored
by connecting a resistor between the sense output
terminal 1E and GND and another resistor
between sense output terminal 2E and GND.
External high-speed output-clamp diodes should be used for inductive transient suppression. To minimize
device power dissipation, a VCC1 supply voltage, separate from VCC2, is provided for the logic inputs.
The TPIC0298 is designed for operation from 0°C to 70°C.

NOTES: 1. All voltage values are with respect to the network GND, unless otherwise noted.
2. The maximum current limitation at this terminal generally occurs at a voltage of lower magnitude than the voltage limit. Neither the
maximum current nor the maximum voltage for this terminal should be exceeded.
3. Combined output current applies to each of the two full-H drivers individually. This current is the sum of the currents at outputs 1Y1
and 1Y2 for full-H driver 1 and the sum of the currents at outputs 2Y1 and 2Y2 for full-H driver 2. The full-H drivers can carry the rated
combined current simultaneously.
4. For operation above 25°C free-air temperature, derate linearly at the rate of 28.6 mW/°C. For operation above 75°C case temperature,
derate linearly at the rate of 333 mW/°C. Due to variations in individual device electrical characteristics and thermal resistance, the
built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation.

APPLICATION INFORMATION
This circuit shows one half of a TPIC0298 used to provide full-H bridge drive for a 24-V, 2-A dc motor . Speed control
is achieved with a TLC555 timer. This provides variable duty-cycle pulses to the EN input of the TPIC0298. In this
configuration, the operating frequency is approximately 1.2 kHz. The duty cycle is adjustable from 10% to 90% to
provide a wide range of motor speeds. The motor direction is determined by the logic level at the direction control
input. The circuit can be enabled or disabled by the logic level at the EN input. A 5-V supply for the logic and timer
circuit is provided by a TL431 shunt regulator. For circuit operation, refer to the function table.
