2A H-Bridge Driver

Description

Features

The CS3720 is high current (2A typ)

bidirectional DC motor driver. The

H-bridge output stage consists of

two pairs of power NPN transis-

tors, each with a V_SAT=2.3V at

I_OUT=2A (typ).

ENABLE2 is high, DIRECTION

determines which way current

flows through the motor coil. Any

other combination of ENABLE set-

tings disables the outputs.

■ TTL compatible

DIRECTION Control

■ Fault Protection

The CS3720 is protected against

overvoltage fault conditions. If a

fault condition is detected, the IC

shuts down.

The three TTL compatible inputs,

ENABLE1, ENABLE2, and DIREC-

TION control the output stage.

When ENABLE1 is low and
