Product Summary

The M5232L is a unique semiconductor integrated circuit designed for use as a voltage detector/on-off alarm circuit. Housed in a compact 8-pin SIP, the M5232L contains a comparator, reference voltage sourse, a vibrator circuit for turning the LED on and off, and a voltage regulation circuit. The applications of the M5232L include low voltage checker for batteries in equipment such as radio/cassette recorders, portable VCRs, cameras, Alarm and protection circuits of electronic equipment.

Parametrics

M5232L absolute maximum ratings: (1)Supply voltage: 20V; (2)Power dissipation: 800mW; (3)Load current: 50mA; (4)Thermal derating TA≥25℃: 8mW/℃; (5)Operating temperature range: -20 to 75℃; (6)Storage temperature range: -55 to +125℃.

Features

M5232L features: (1)Starting supply voltage at which the LED will blink can be set optionally by using external resistors Ri and R2 (in the case of a low voltage checker for batteries); (2)LED on/off frequency can be set optionally with external capacitor C1; (3)Buily-in logic output pin (Pin(6) causes a high-to-low level transition as soon as the blinking begins; (4)Hysteresis operation is possible at the blink starting voltage using Pin6; (5)LED lights when the input voltage of the comparator at Pin7 is higher than the internal reference voltage, permitting the M5232L to be used as a pilot lamp for power ON indication.
