CG8010

POWER SUPPLY SUPERVISOR WITH PWM CONTROLLER

complete power supervisor for use in the switched mode power supply .

It contains various functions, like under voltage protection (UVP), over voltage

protection (OVP), power good output (PG) and ON/OFF control (REM).

UVP(Under voltage protection) function is for +3.3V, +5V, +12V outputs. OVP(Over voltage protection) function is for +3.3V, +5V, +12V and PT is for

extra protection input.

PG(Power good signal) is a safe operation signal to inform the external parts. REM(Remote on/off) is used to control the SMPS on/off. The REM control

signal has the on/off transferred debounce–time.

FEATURE

■ 3-channel under voltage protection (UVP) ■ 3-channel over voltage protection (OVP) ■ 1-channel extra protection (PT) ■ 1-channel sense input to control the PG (SEN) ■ Remote on/off control function (REM) ■ Dual output for push-pull operation (OP1/OP2) ■ Soft start capability by external capacitor (SS) ■ VCC under voltage lockout ■ 16-Pin dual in-line package ■ Pb-free Package are available
