MAX16020 - (MAX160xx) Low-Power uP Supervisory Circuits

General Description

The MAX16016/MAX16020/MAX16021 supervisory circuits monitor power supplies, provide battery-backup control, and chip-enable (CE) gating to write protect memory in microprocessor (µP)-based systems.

Key Features

  • section. The MAX16016/MAX16020/MAX16021 operate from a 1.53V to 5.5V supply voltage and offer fixed reset thresholds for monitoring 5V, 3.3V, 3V, 2.5V, and 1.8V systems. Each device is available with either a pushpull or open-drain reset output. The MAX16016/MAX16020/MAX16021 are available in small TDFN/TQFN packages and are fully specified for an operating temperature range of -40°C to +85°C. Features o System Monitoring for 5V, 3.3V, 3V, 2.5V, or 1.8V Power-Supply Voltages o 1.53V to 5.5V Ope.

19-4145; Rev 2; 10/08 www.DataSheet4U.com Low-Power µP Supervisory Circuits with Battery-Backup Circuit and Chip-Enable Gating General Description The MAX16016/MAX16020/MAX16021 supervisory circuits monitor power supplies, provide battery-backup control, and chip-enable (CE) gating to write protect memory in microprocessor (µP)-based systems. These low-power devices improve system reliability by providing several supervisory functions in a small, single integrated solution. The MAX16016/MAX16020/MAX16021 perform four basic system functions: 1) Provide a µP reset output during VCC supply powerup, power-down, and brownout conditions.
