Quadruple Voltage Monitor
The ISL88042 is a Quadruple voltage-monitoring supervisor
combining competitive reset threshold accuracy and low
power consumption. This device combines popular functions
such as Power-On Reset, Undervoltage Supply Supervision,
reset signaling and Manual Reset. Monitoring four different
supplies in a 8 Ld 2x3 TDFN package, the ISL88042 devices
can help to lower system cost, reduce board space
requirements, and increase the reliability of multi-voltage
systems.
Low V DD detection circuitry protects the user ’s system from
low voltage conditions, resetting the system when V DD or
any of the other monitored power supply voltages fall below
their respective minimum voltage thresholds. The reset
signal remains asserted until all of these voltages return to
proper operating levels and stabilize.
Two of the four voltage monitors have preset thresholds for
either dual 3.3V or one each for one 5V and one 3.3V
supplies. Users can adjust the threshold voltages of the third
and fourth voltage monitors in order to meet specific system
level requirements.
