Description
The MAX691EWE+ model is a part of the MAX690 family of supervisory circuits used in microprocessor systems for power supply monitoring and battery control functions. They reduce the complexity and number of components needed for various functions like µP reset and backup-battery switchover, watchdog timer, CMOS RAM write protection, and power-failure warning, and improve system reliability and accuracy compared to separate ICs or discrete components.
Specifications and Features
- Supervisory function integration saves board space while fully protecting microprocessor-based systems.
- Precision voltage monitor:
- 4.65V (MAX690, MAX691, MAX694, MAX695)
- 4.40V (MAX692, MAX693)
- Power OK/reset time delay:
- 50ms, 200ms, or adjustable
- Watchdog timer:
- 100ms, 1.6s, or adjustable
- Battery backup power switching
- Voltage monitor for power fail or low battery warning
- Minimum external component count
- Low power consumption in battery backup mode extends battery life with 1µA standby current
- Onboard gating of chip enable signals protects against erroneous data written to RAM during low VCC events.
