4-Channel Supervisor IC for Power Supply

Applications

Features

ꢀ

PC power supply

ꢀ

Over-voltage protection and lockout for 3.3V,

ꢀ

LCD TV power supply

5V, and two 12V power supplies

Under-voltage protection and lockout for 3.3V,

5V, and two 12V power supplies

Over-current protection and lockout for 3.3V,

Description

The GR8324N is designed to monitor the outputs of

switching power supply and generates the power

good signal to inform the system. It provides

over-voltage protection, under-voltage protection,

over-current protection, and power good signal

generating. The over-voltage protection (OVP) and

under-voltage protection (UVP) monitor 3.3V, 5V

and two 12V to protect the power supply and system.

Over-current protection (OCP) monitors IS33, IS5,

IS12A, IS12B input current sense. An adjustable

over-current trip point composed of Iref and a setting

resistor help users design the OCP easily. The

power-good feature issues a power-good signal

when the output is ready; therefore, the GR8324N

provides a reliable power supply environment for the

system.

ꢀ

75mS delay for under-voltage and over-current

protection

ꢀ

38mS for PSON/ de-bounce

73uS width noise de-glitches

Wide power supply voltage range

Special care for AC power off

Programmable protection circuit

Brown-in auto recovery
