Micropower, Latching Voltage Monitors

in SOT23-5

General Description

The MAX834/MAX835 micropower voltage monitors

contain a 1.204V precision bandgap reference, com-

parator, 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 oscil-

lations in battery-load-disconnect applications.
