Rainbow Electronics MAX835 - Manual

_______________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.
________________________Applications
