BD65491FV,BD65492MUV
No.11014EAT05
●Description
The BD65491FV motor driver provides 1 Full-ON Drive H-bridge channel, while BD65492MUV provides 2 Full-ON Drive
H-bridge channels. These lens driver series feature wide range operating from 1.8V and low power consumption by high
switching speed in a compact surface mount package.
●Features
1) Low ON-Resistance Power DMOS output:
Full-ON Drive block with 0.35Ω Typ. (BD65491FV)
Full-ON Drive block with0.9Ω Typ. (BD65492MUV)
2) Range of motor power supply voltage: 1.8V to 16.0V
3) Charge pump-less type with p-channel DMOS for the upper side transistor
4) The highest performance in regard to switching speed, and 4-values selection
Turn On Time: 150ns (BD65491FV), 200ns (BD65492MUV)
Turn Off Time: 50ns(BD65491FV), 80ns(BD65492MUV)
5) Drive mode switch function
6) Maximum output current for H-bridge:
DC maximum 1.2A (BD65491FV), 1.0A (BD65492MUV)
Peak maximum 4.0A (BD65491FV)
7) Control input pins corresponding to the signal of 1.8V system
8) Built-in UVLO (Under Voltage Lockout Protection) function and TSD (Thermal Shut Down) circuit
9) Standby current: 0μA Typ.
