It is designed to drive inductive loads such as relays, solenoids, dc motors, stepping motors, and other highcurrent 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 pseudoDarlington 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 highimpedance 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. 2E 2Y2 2Y1 2A2 2EN 2A1 VCC1 GND 1A2 1EN 1A1 VCC2 1Y2 1Y1 1E 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 1A1 1EN 1A2 2A1 2EN 2A2 2 5 6 EN 7 EN X 1 3 13 10 EN 11 X EN 12 15 14 1Y1 1E 1Y2 2Y1 2E 2Y2 This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.

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 25C free-air temperature, derate linearly at the rate of 28.6 mW/C. For operation above 75C 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. 2-4 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 TPIC0298 DUAL FULL-H DRIVER SLIS006 - D2942, JUNE 1987 - REVISED JANUARY 1990 recommended operating conditions Logic supply voltage, VCC1 Output supply voltage, VCC2 MIN MAX 4.5 7 V 5 46 V - 0.5 2 Emitter terminal (1E or 2E) voltage, VE (see Note 5) VCC1 - 3.5 VCC2 - 4 2.3 A High level input voltage, High-level voltage VIH (see Note 5) VCC1 VCC2 - 2.5 UNIT V V 2.3 7 - 0.3 VCC1 1.5 V Output current, IO 2 A Communication frequency 40 kHz EN Low-level input voltage at A or EN, VIL Operating free-air temperature, TA 0 70 C The algebraic convention, in which the least positive (most negative) limit is designated as minimum, is used in this data sheet for emitter terminal voltage and logic voltage levels.

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.
