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 16-pin SSOP package. This allows for simplified peripheral circuit as well as compact and thin set design.

Features

• Direct drive to n-ch/p-ch MOSFET

• Fixed output duty: 45

• Output current (peak): ±300 mA

• Light control

― Pulse synchronous control

Output OFF period is adjusted synchronous with the OSC frequency. (1 kHz-200 kHz)

― 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)

Application

LCD Back-light control for Note P.C etc.
