MAX6832–MAX6840
Ultra-Low-Voltage SC70 Voltage Detectors
and μP Reset Circuits
General Description
The MAX6832 –MAX6840 are microprocessor (μP)
supervisory circuits used to monitor low-voltage power
supplies in μP and digital systems. They provide excel-
lent circuit reliability and low cost by eliminating exter-
nal components and adjustments when used with
+1.2V to +1.8V powered circuits.
These devices assert a reset signal whenever the V CC
supply voltage declines below a preset threshold or
whenever manual reset ( MR ) is asserted. Reset remains
asserted for a fixed timeout delay after V CC has risen
above the reset threshold or when manual reset is
deasserted. Five different timeout periods are available:
70μs (voltage detector), 1.5ms, 30ms, 210ms, and 1.68s.
Reset thresholds suitable for operation with a variety of
supply voltages are available.
The MAX6832/MAX6835/MAX6838 have a push-pull
active-low reset output ( RESET ). The MAX6833/
MAX6836/MAX6839 have a push-pull active-high reset
output (RESET) and the MAX6834/MAX6837/MAX6840
have an open-drain active-low reset output ( RESET ). The
open-drain active-low reset output requires a pullup resis-
tor that can be connected to a voltage higher than V CC .
The MAX6835/MAX6836/MAX6837 feature a debounced
manual reset input ( MR ), while the MAX6838/MAX6839/
MAX6840 provide a RESET-IN input allowing the user to
externally adjust the reset threshold. The reset compara-
tor is designed to ignore fast transients on V CC .
Low supply current of 7.5μA makes the MAX6832 –
