MOS INTEGRATED CIRCUIT
µPD16823
MONOLITHIC H BRIDGE DRIVER
DESCRIPTION
This IC is a monolithic H bridge driver employing a horizontal N-channel power MOS FET for its driver stage.
It is provided with forward/reverse and brake functions and is ideal as a driver circuit for a motor that winds or
rewinds the film in a camera, or a motor for moving a lens.
FEATURES
• High drive current IDR1 = 0.5 A (DC)
IDR2 = 1 A: at PW ≤ 200 ms, duty cycle ≤ 50%
IDR3 = 3 A: at PW ≤ 200 ms, single pulse
• 1.5ch H bridge circuits
• Low ON resistance (sum of ON resistance of top and bottom FETs)
RON = 0.6 Ω TYP. at IDR = 0.5 A
• Standby function that turns OFF charge pump circuit
• Low-voltage drive (2.5 V MIN.)
• Surface-mount mini-mold package: 20-pin plastic SOP (300 mil)
