TOSHIBA CD process Integrated Circuit Silicon Monolithic
Dual H Bridge driver IC
The TC78H660FNG is a dual H Bridge driver IC which incorporates DMOS
with low on-resistance in output transistors.
It can control two DC brushed motors or one stepping motor.
Weight: 56.5 mg (typ.)
Built-in Dual H Bridge
PWM controlled constant-current drive
Power supply operating voltage: 2.5 V to 16.0 V
Output current ratings: 2.0 A (max)
Low on-resistance (High + Low side = 0.48 Ω (typ.)) MOSFET output stage
Built-in Sense resistor less current control architecture (Advanced Current Detection System)
Multi error detect functions (Thermal shutdown (TSD), Over current (ISD)) and Under voltage lockout(UVLO))
Error detection (TSD/ISD) flag output function
Built-in VCC regulator for internal circuit
Chopping frequency of a motor can be adjusted by external resistor
Selectable Forward / Reverse / Stop / Brake modes
Note: Please be careful about thermal conditions during using.
