DS1236-10

The DS1236-10 MicroManager chip from Analog Devices Inc. is designed for microprocessor-based systems, offering essential functions for power supply monitoring, reset control, and memory backup. It features a precise internal voltage reference and comparator circuit to monitor power supply status, ensuring an orderly shutdown when an out-of-tolerance condition occurs. The chip can halt and restart an out-of-control microprocessor, monitor a pushbutton for external override, and warn of impending power failures.

Key electrical specifications include a 4.37V nominal voltage monitoring capability, active high/active low reset outputs, and an open-drain/push-pull output configuration. It provides a reset timeout of 25ms minimum and consumes less than 100 nA of battery current at 25°C. The device operates within a temperature range of 0°C to 70°C (TA).

Packaged in a 16-pin DIP (0.300", 7.62mm) format, the DS1236-10 is designed for through-hole mounting. It also offers features like an early warning input for non-maskable interrupts and controls external power switches for high-current applications. The optional industrial temperature range of -40°C to +85°C is also available.

This component is suitable for nonvolatile microprocessor applications and low-power "stop mode" in battery-operated hand-held devices, providing necessary control for orderly shutdown and startup in battery backup scenarios.
