MAX836, MAX837
4-Pin Micropower Voltage Monitors
Low-Power SOT Voltage Monitors
|
Status
Active: In Production.
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.
