µPD16805
Brush DC Motor Driver
Monolithic H Bridge Driver Circuit
Overview
The µPD16805 is a monolithic H bridge driver IC which uses low-ON resistance power MOS FETs in its driver stage.
This driver has a forward, reverse, and brake functions and is ideal for the driver circuit of motors for camera that advance or rewind the film, and for auto focusing or zooming.
This IC supports a drive current of up to 1.0 A (DC).
Features
- High drive current
IDR = 4.2 A MAX. at PW <= 200 ms (single pulse)
IDR = 1.0 A (DC) - Low-ON resistance(sum of ON resistances of top and bottom MOS FET)
RON = 0.4 Ω TYP. at IDR = 1.0 A - Standby function that turns OFF charge pump circuit
- Compact surface mount package
16-pin plastic SOP
