Detailed Description
The MAX16072/MAX16073/MAX16074 ultra-small, ultra-
low-power, P supervisory circuits feature a precision
band-gap reference, comparator, and internally trimmed
resistors that set specified trip threshold voltages.
Designed to monitor the system supply voltage and an
output during power-up, power-down, and brownout
conditions, these devices provide excellent circuit reli-
ability and low cost by eliminating external components
and adjustments when monitoring nominal system volt-
age from 1.8V to 3.6V.
The MAX16072 has a push-pull active-low reset output,
the MAX16073 has a push-pull active-high reset output,
and the MAX16074 has an open-drain active-low reset
output. The devices are designed to ignore fast tran-
sients on VCC. The devices also include a manual reset
input (MR). When MR is low, reset is asserted. When MR
is high and VCC is above the detector threshold (VTH),
reset is not asserted.
Supply and Monitored Input (VCC)
The MAX16072/MAX16073/MAX16074 operate with a
VCC supply voltage from 1.2V to 2.75V. VCC has a rising
threshold of VTH + VHYST and a falling threshold of VTH.
When VCC rises above VTH + VHYST and MR is high,
RESET goes high (RESET goes low) after the reset time-
out period (tRP). See Figure 1.
When VCC falls below VTH, RESET goes low (RESET
goes high) after a fixed delay (tRD).
