MAX834

19-1157; Rev 0; 12/96 Micropower, Latching Voltage Monitors in SOT23-5 _______________General Description The MAX834/MAX835 micropower voltage monitors contain a 1.204V precision bandgap reference, comparator, and latched output in a 5-pin SOT23 package. Using the latched output prevents deep discharge of batteries. The MAX834 has an open-drain, N-channel output driver, while the MAX835 has a push/pull output driver. Two external resistors set the trip-threshold voltage. The MAX834/MAX835 feature a level-sensitive latch, eliminating the need to add hysteresis to prevent oscillations in battery-load-disconnect applications. ____________________________Features o Prevents Deep Discharge of Batteries o Precision ±1.25% Voltage Threshold o Latched Output (once low, stays low until cleared) o SOT23-5 Package o Low Cost o Wide Operating Voltage Range, +2.5V to +11V o <2µA Typical Supply Current o Open-Drain Output (MAX834) Push/Pull Output (MAX835) MAX834/MAX835 ________________________Applications Precision Battery Monitor Load Switching Battery-Powered Systems Threshold Detectors ______________Ordering Information PART MAX834EUK-T MAX835EUK-T TEMP.
