DATASHEET ISL88001, ISL88002, ISL88003 Ultra Low Power 3 Ld Voltage Supervisors in SC-70 and SOT-23 Packages FN6174 Rev 3.00 Feb 10, 2021 The ISL88001, ISL88002, ISL88003 supervisors are extremely low power 160nA voltage supervisors that help to monitor the power supply voltages in a wide variety of applications. By providing Power-On Reset and supply voltage supervision in small 3 Ld SC-70 and SOT-23 packages, the ISL88001, ISL88002, ISL88003 devices can help to lower system cost, reduce board space requirements and increase the reliability of systems. The most popular voltage trip points are available for standard power supplies from 1.8V to 5.0V (see “Ordering Information” on page 3). These reset threshold voltages are accurate to within ±1.2% and the reset signal is valid down to 1V. Active high and active low reset outputs are available in push-pull and open drain configurations (see “Functional Block Diagrams” on page 2). The ISL88001, ISL88002, ISL88003 devices are specifically designed for low power consumption and high threshold accuracy, making them especially suitable for electronic devices and portable equipment.

The RST pin is an active-low reset output that is pulled to GND (LOW) when reset is asserted. The ISL88001 is push-pull while the ISL88002 is open drain. The RST pin is a push-pull active-high reset output that is pulled to VDD (HIGH) when reset is asserted. Supply Voltage and Monitored Input. The VDD pin is the IC power supply terminal and also the monitored input.
