Pin Name
Pin Function
1
RST
Reset (Digital Output): Active-high output. Asserted when V
IN
falls below
V
THU
(undervoltage threshold), or rises above V
THO
(overvoltage threshold).
Deasserted no less than 140ms after V
IN
returns within threshold limits.
High-Voltage Flag (Open-Drain Output): /HV is asserted (active low) when
the input voltage exceeds the V
THO
(overvoltage threshold). It indicates
power supply overvoltage and is intended for connection to a protection
device such as a “crowbar” circuit.

VIN
Analog Input: Voltage monitor input and power supply input to the IC.
4
/RST
Reset (Digital Output): Active-low digital output. This output will be asserted
whenever V
IN
falls below V
THU
(undervoltage threshold), or rises above
V
THO
(overvoltage threshold). It will be deasserted no less than 140ms after
V
IN
returns within the threshold limits.
Ground: Ground return for all IC functions.

5
/MR
Manual Reset (Digital Input): Logic low initiates immediate, unconditional
reset. If V
IN
is within tolerance thresholds, when /MR is released (returns
high), the reset output(s) will be deasserted no less than 140ms later. /MR
may be driven by a CMOS or TTL logic signal or a mechanical switch.
(Switch debouncing is performed internally.) /MR has an internal pull-up to
VIN and may remain open if unused.
