Product Summary

The DS1233M-5 is a voltage monitor. The DS1233M-5 uses a precision temperature-compensated reference and comparator circuit to monitor the status of the power supply (VCC). When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces reset to the active (low) state. When VCC returns to an intolerance condition, the reset signal is kept in the active state for approximately 350 ms to allow the power supply and processor to stabilize.

Parametrics

DS1233M-5 absolute maximum ratings: (1)Voltage on VCC Pin Relative to Ground -0.5V to +7.0V; (2)Voltage on I/O Relative to Ground -0.5V to VCC + 0.5V; (3)Operating Temperature -40℃ to +85℃; (4)Storage Temperature -55℃ to +125℃; (5)Soldering Temperature 260℃ for 10 seconds.

Features

DS1233M-5 features: (1)Automatically restarts microprocessor after power failure; (2)Maintains reset for 350 ms after VCC returns to an in-tolerance condition; (3)Reduces need for discrete components; (4)Precision temperature-compensated voltage reference and voltage sensor; (5)Low-cost TO-92 package or surface mount 8-pin SOIC packages available; (6)Internal 5 kΩ pullup resistor; (7)Compatible with Motorola 68XXX series and HC16 Microprocessors; (8)Pin function compatible with the Motorola MC33064, MC34064, MC33164, and MC34164; (9)Operating temperature of -40℃ to +85℃.
