General Description

VBAT VCCO VCC GND PF PF WC/ SC RC IN NMI ST CEO CEI PBRST RST RST - +3-Volt Battery Input - Switched SRAM Supply Output - +5-Volt Power Supply Input - Ground - Power-Fail (Active High) - Power-Fail (Active Low) - Wake-Up Control (Sleep) - Reset Control - Early Warning Input - Non-Maskable Interrupt - Strobe Input - Chip Enable Output - Chip Enable Input - Pushbutton Reset Input - Reset Output (Active Low) - Reset Output (Active High) DESCRIPTION The DS1236 MicroManager Chip provides all the necessary functions for power supply monitoring, reset control, and memory backup in microprocessor-based systems.

A precise internal voltage reference and comparator circuit monitor power supply status.

When an out-of-tolerance condition occurs, the microprocessor reset and power-fail outputs are forced active, and

Key Features

  • Holds microprocessor in check during power transients Halts and restarts an out-of-control microprocessor Monitors pushbutton for external override Warns microprocessor of an impending power failure Converts CMOS SRAM into nonvolatile memory Unconditionally write-protects memory when power supply is out of tolerance Consumes less than 100 nA of battery current at 25°C Controls external power switch for high current.
