AT214E
1. GENERAL DESCRIPTION
is a single-chip bi-directional motor driver CMOS IC for low-voltage applications. It is designed by
AT214
LSI high technology with a low-power and low-cost process. It has H bridge driver of built-in MOSFET power
switch to provide Forward / Reverse / Brake / Stop function for motor driver applications.
2. FEATURES
(1). Wide operating voltage: 1.8V ~ 9.0V.
(2). H bridge driver of internal PMOS/NMOS power switches.
(3). Support 4 operating mode: Forward / Backward / Brake / Stop.
(4). Low standby current.
(Typ.=0.1uA)
(5). Over
800mA output current capability.
(6). Built-in Thermal Shutdown (TSD) circuit.
(7).
CMOS input. Built-in input pull-low resistance and no current-limit resistance required.
(8). High 5KV Human Body Mode (HBM) ESD protection.
