UPD16805 Description
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).
UPD16805 Key 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
- pact surface mount package 16-pin plastic SOP (300 mil)
