MAX6895MAX6899 Ultra-Small, Adjustable Sequencing/ Supervisory Circuits General Description Features 1.8% Accurate Adjustable Threshold Over The MAX6895MAX6899 is a family of small, low- Temperature power, voltage-monitoring circuits with sequencing capability. These miniature devices offer tremendous Operate from V of 1.5V to 5.5V CC flexibility with an adjustable threshold capable of monitoring Capacitor-Adjustable Delay down to 0.5V and an external capacitor-adjustable time Active-High/-Low Enable Input Options delay. These devices are ideal for use in power-supply Active-High/-Low Output Options sequencing, reset sequencing, and power-switching applications. Multiple devices can be cascaded for complex Open-Drain (28V Tolerant)/Push-Pull Output Options sequencing applications. Low Supply Current (10A, typ) A high-impedance input with a 0.5V threshold allows an external resistive divider to set the monitored threshold. Fully Specified from -40C to +125C The output asserts (OUT = high or OUT = low) when Ultra-Small 6-Pin DFN Package or Thin SOT23 the input voltage rises above the 0.5V threshold and Package the enable input is asserted (ENABLE = high or AEC-Q100 Qualified (MAX6896AAZT/V+, ENABLE = low).

Pin Configurations The MAX6895A/P offers an active-high enable input and an active-high push-pull output. The MAX6896A/P TOP VIEW V CDELAY OUT CC offers an active-low enable input and an active-low 6 5 4 push-pull output. The MAX6897A/P offers an active- high enable input and an active-high open-drain MAX6895 MAX6897 out-put. Finally, the MAX6898A/P offers an active-low MAX6899 enable input and an active-low open-drain output. The 1 2 3 MAX6899A/P offers an active-low enable with an active- ENABLE GND IN high push-pull output.
