KA3501

PC SMPS Supervisory IC

Features

Description

• Complete House Keeping Circuit

• Few External Components

• Positive Voltage Protection

The KA3501 is complete housekeeping circuits for use in the

secondary side of SMPS(Switched Mode Power Supply).

This IC(Integrated Circuit) contains a precision voltage

reference, protection circuits and a power good signal

generator. It also has a high current drive output for use in

conjunction with an external "crowbar" SCR. The reference

voltage is trimmed to ±2% for correct output voltages(+5V/

+12V) and power good signal generator is to monitor the

voltage level of power good supply for safe operation in a

microprocessor circuit. Using the KA3501 requires few

external components to accomplish a complete

• Negative Voltage Protection

• High Current Drive Output for SCR

• Precision Voltage Reference for 5V/12V Outputs

• Power Good Signal Generator with Hysteresis

housekeeping circuit for SMPS(Switched Mode Power

Supply). The KA3501 is available in an 14-pin DIP.
