Description

FULL DATA SHEET Download Rev 4 (PDF, 216kB) E-Mail 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: Provide a µP reset output during VCC supply power-up, power-down, and brownout conditions. Control VCC to battery-backup switching internally to maintain data or low-power operation for memories, real-time clocks (RTCs), and other digital logic when the main power is removed. Provide memory write protection through internal chip-enable gating during brownout. Provide a combination of additional supervisory functions listed in the Features section in the full data sheet. 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 push-pull 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.
