The MAX807LEWE+ from Analog Devices is a microprocessor supervisory circuit that simplifies power-supply and battery-control monitoring in µP systems. It offers a precision 4.675V voltage monitoring capability, reducing the complexity and component count required for reliable operation.
This supervisory circuit provides both active-high and active-low RESET outputs, ensuring the system is in a correct state during power-up, power-down, and brownout conditions. It includes a reset timeout of 140ms minimum and a power-OK/reset time delay of 200ms. The device also features an independent watchdog timer to monitor µP activity.
Designed for portable and higher-performance equipment, the MAX807LEWE+ operates within a temperature range of -40°C to 85°C. It supports backup-battery switchover and write protection for CMOS RAM or EEPROM. The component is housed in a 16-SOIC package suitable for surface mounting.
Key features include a 2ns chip-enable gate propagation delay and power switching capabilities of 250mA in VCC mode and 20mA in battery-backup mode. Its low standby current of 1µA makes it ideal for battery-powered applications.
