LV8761V Forward/Reverse H-bridge Driver
Overview
The LV8761V is an H-bridge driver that can control four operation modes (forward, reverse, brake, and standby) of a
motor. The low on-resistance, zero standby current, highly efficnet IC is optimal for use in driving brushed DC motors for
office equipment.
Features
• Forward/reverse H-bridge motor driver: 1 channel
• Built-in current limiter circuit
• Built-in thermal protection circuit
• Built-in short-circuit protection function
• Unusual condition warning output pin
• Short-circuit protection circuit selectable from latch-type or auto reset-type

Setting the current limit value
When VCC = 5V,
Vref = 1.5V
Ilimit = Vref/5/RNF
= 1.5V/5/0.22Ω = 1.36A
Setting the current limit regeneration time and short-circuit detection time
Tscp ≈ C × V/I
= 100pF × 1V/5μA
