µPD16805
MONOLITHIC H BRIDGE DRIVER CIRCUIT
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).
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 (300 mil)
