The MAX6870/MAX6871 EEPROM-configurable, multi-voltage supply sequencers/supervisors monitor several voltage detector inputs, two auxiliary inputs, and four general-purpose logic inputs.
The MAX6870 and MAX6871 are EEPROM‑configurable, multi‑voltage supply sequencers and supervisors that monitor multiple voltage detector inputs, auxiliary inputs, and general‑purpose logic inputs. They provide programmable outputs for flexible power‑supply sequencing and system reset/interrupt control.
Key features include configurable voltage‑detector thresholds, programmable timing delays, a 10‑bit internal ADC, SMBus/I²C‑compatible serial interface, and operation over a -40 °C to +85 °C temperature range. The devices are offered in a 32‑pin thin QFN package and are used in telecommunications, networking, servers, base stations, and other high‑density electronic systems.
