DESCRIPTION
M62295GP is a semiconductor integrated circuit designed for PC
back- light control, which employs 2 output totempole output circuit
specifically suitable for inverter drive with piezo device.
Such necessary functions as light control, protection circuit are
housed in 16pin SSOP package. This allows for simplified peripheral
circuit as well as compact and thin set design.
Direct drive to n-ch/ p-ch MOSFET
Fixed output duty: 45%
Output current (peak) : ± 300mA
Light control
Pulse synchronous control
Output OFF period is adjusted synchronous with the OSC
frequency (1kHz-200kHz).
Light control available from 10%(MIN.) up to 100% by the
voltage applied from outside (Adj2 terminal).
Protection functions
2 kinds of timer-latch time setting available by 3 triggers
(few seconds, several tens of seconds set by external capacitor)
