The TPIC0108B is a PWM control intelligent H-bridge designed specifically for dc motor applications. The
device provides forward, reverse, and brake modes of operation. A logic supply voltage of 5 V is internally
derived from V_CC.
The TPIC0108B has an extremely low r_DS(on), 280 mΩ typical, to minimize system power dissipation. The
control inputs (IN1 and IN2) greatly simplify the microcontroller overhead requirement. The device has a low
quiescent supply current of 20 µA to suit a wide range of automotive and industrial battery-operated
applications.
The TPIC0108B provides protection against over-voltage, over-current, over-temperature, and cross
conduction faults. Fault diagnostics can be obtained by monitoring the STATUS1 and STATUS2 terminals and
the two input control lines. STATUS1 is an open-drain output suitable for wired-or connection. STATUS2 is a
push-pull output that provides a latched status output. Under-voltage protection ensures that the outputs, OUT1
and OUT2, will be disabled when V_CC is less than the under-voltage detection voltage V_(UVCC).
The TPIC0108B is designed using TI’s LinBiCMOS™ process. LinBiCMOS allows the integration of low power
CMOS structures, precision bipolar cells, and low impedance DMOS transistors.
The TPIC0108B is offered in a 20-pin thermally enhanced small-outline package (DWP) and is characterized
for operation over the operating case temperature of –40°C to 125°C.
