General Description

The MAX6375–MAX6380 are ultra-low-power circuits used for monitoring battery, power-supply, and regulat ed system voltages. Each detector contains a precision bandgap reference, comparator, and internally trimmed resistors that set specified trip threshold voltages.  These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from 2.5V to 5V.

Features

♦ Ultra-Low 500nA Supply Current (MAX6375/MAX6376/MAX6377)

♦ Thresholds Available from 2.20V to 4.63V in Approximately 100mV Increments

♦ ±2.5 Threshold Accuracy Over Temperature

♦ Low Cost

♦ Available in Three Versions: Push-Pull OUT, Push-Pull OUT, and Open-Drain OUT

♦ Power-Supply Transient Immunity

♦ No External Components

♦ Available in Either a 3-Pin SC70 or 3-Pin SOT23 Package
