Features Complete House Keeping Circuit Few External Components Positive Voltage Protection Negative Voltage Protection High Current Drive Output for SCR Precision Voltage Reference for 5V/12V Outputs Power Good Signal Generator with Hysteresis
DescriptionThe 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
housekeeping circuit for SMPS(Switched Mode Power
Supply). The KA3501 is available in an 14-pin DIP.
