TB67H400AHG
PWM Chopper-Type Brushed DC Motor driver
The TB67H400AHG is brushed DC motor driver of a PWM chopper-type.
The TB67H400AHG is a dual channel H-SW driver which can control two
brushed DC motors. Moreover, the parallel control function (Large mode) of an
output part is built in, and 1ch high current drive is also possible. Fabricated
with the BiCD process, the TB67H400AHG is rated at 50 V, 4.0 A (2ch)/8.0 A
(1ch).
Features
Monolithic motor driver using BiCD process.
Capable of controlling two brushed DC motor.
2 drive modes (PWM controlled constant current/ direct PWM)
4 operation modes (Clock-wise/Counter clock-wise/Brake/Stop (Off))
Low on-resistance output stage (High side+Low side:0.49 Ω (typ.))
High voltage and current (for specification, please refer to absolute
maximum ratings and operating ranges.)
Built-in error detection circuits (Thermal shutdown (TSD), over-current
detection (ISD), and power-on reset (POR)).
The VCC regulator for internal circuit operation is built in.
Able to customize PWM (internal chopping) frequency by external
components.
Note: Please be careful about the thermal conditions during use.
