description  
The TPIC0107B 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 TPIC0107B has an extremely low r  
, 280 mtypical, to minimize system power dissipation. The  
DS(on)  
direction control (DIR) and PWM control (PWM) inputs greatly simplify the microcontroller overhead  
requirement. The PWM input can be driven from a dedicated PWM port while the DIR input is driven as a simple  
low speed toggle.  
The TPIC0107B 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  
is less than the under-voltage detection voltage V  
.
CC  
(UVCC)  
The TPIC0107B 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 TPIC0107B 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.
