Rainbow Electronics MAX837 - Manual

_______________General Description
The MAX836/MAX837 micropower voltage monitors
contain a 1.204V precision bandgap reference and a
comparator in a SOT143 package. The MAX836 has an
open-drain, N-channel output driver, while the MAX837
has a push-pull output driver. Two external resistors set
the trip threshold voltage.
