DATASHEET ISL88001, ISL88002, ISL88003 FN6174 Rev 3.00 Feb 10, 2021 Ultra Low Power 3 Ld Voltage Supervisors in SC-70 and SOT-23 Packages 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. Features 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). • 190ms Power-On Reset Timeout • Single Voltage Monitoring Supervisors • Fixed-Voltage Options Allow Precise Monitoring of +1.8V, +2.5V, +3.0V, +3.3V, and +5.0V Power Supplies • Ultra Low 160nA Supply Current • ±1.2% Voltage Threshold Accuracy • Reset Signal Valid Down to VDD = 1V • No External Components Necessary • Immune to Power-Supply Transients • Available in Small 3 Ld SC-70 and 3 Ld SOT-23 Pb-free Packages 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. • Pin Compatible with MAX803, MAX809, MAX810 Pinouts • Microprocessor/Microcontroller Systems ISL88001, ISL88002 (3 LD SC-70, 3 LD SOT-23) TOP VIEW • Pb-Free (RoHS Compliant) Applications • Intelligent Instruments • Controllers • Computer Systems GND 1 • Portable/Battery-Powered Equipment • PDA and Hand-Held PC Devices ISL88001 ISL88002 RST 3 VDD 2 ISL88001 has a push-pull RST output ISL88002 has an open-drain RST output ISL88003 (3 LD SC-70, 3 LD SOT-23) TOP VIEW GND 1 ISL88003 RST 3 VDD 2 ISL88003 has a push-pull RST output FN6174 Rev 3.00 Feb 10, 2021 Page 1 of 15 ISL88001, ISL88002, ISL88003 Pin Descriptions PIN ISL88001 ISL88002 ISL88003 PIN NAME 1 1 GND Ground IC reference. RST 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. 2 RST The RST pin is a push-pull active-high reset output that is pulled to VDD (HIGH) when reset is asserted. 3 VDD Supply Voltage and Monitored Input. The VDD pin is the IC power supply terminal and also the monitored input. 2 3 PIN FUNCTION Functional Block Diagrams VDD VDD POR ± VREF RST RST POR VDD ± VREF VDD GND GND ISL88002 ISL88001 VDD POR ± VREF RST VDD GND ISL88003 FN6174 Rev 3.00 Feb 10, 2021 Page 2 of 15 ISL88001, ISL88002, ISL88003 Ordering Information PART MARKING (Note 6) PACKAGE Tape and Reel PKG.

Pin Descriptions RST The ISL88003 push-pull RST output is set to VDD (HIGH) whenever the device is first powered up or VDD falls below its respective minimum voltage sense level. RST The RST output functions identically to the complementary RST output. On the ISL88001, this is a push-pull output. On the ISL88002, it is an open drain output that is pulled to GND (LOW) when reset is asserted. Suggested pull-up RST resistor values are in the range of 5kΩ to 100kΩ. VDD The VDD pin is the power supply terminal. The voltage at this pin is compared against an internal factory-programmed voltage trip point, VTHVDD. A reset is first asserted when the device is initially powered up to ensure that the power supply has stabilized. Thereafter, reset is again asserted whenever VDD falls below VTHVDD. The device is designed with hysteresis to help prevent chattering due to noise. reset signal (RST = LOW or RST = HIGH) to a µP/µC if this voltage is less than the preset voltage trip point. The reset signal prevents system operation during a power failure or brownout condition. This reset signal remains asserted until VDD exceeds the voltage threshold setting for the reset time delay period tPOR. See Figure 2.

TYPICAL APPLICATION DIAGRAM Principles of Operation The ISL88001, ISL88002, ISL88003 devices provide a low power, high accuracy solution for those voltage monitoring applications needing supply voltage supervision with power reset control. By integrating these features into small 3 Ld SC70 and 3 Ld SOT-23 packages and consuming as little as 160nA of supply current, these devices can lower system cost and reduce board space requirements. Low Voltage Monitoring During normal operation, the ISL88001, ISL88002, ISL88003 devices monitor the voltage level of VDD. The device asserts a FN6174 Rev 3.00 Feb 10, 2021 Page 9 of 15 ISL88001, ISL88002, ISL88003 VTH/VPOR VDD 1V tPOR tRPD tPOR RST FIGURE 2. VOLTAGE MONITORING TIMING DIAGRAM Power-On Reset (POR) Applying power to the ISL88001, ISL88002, ISL88003 activates a POR circuit, which asserts reset once VDD = 1 V. (i.e. RST goes LOW). This provides several benefits: • It prevents the system microprocessor from starting to operate with insufficient voltage. • It prevents the processor from operating prior to stabilization of the oscillator. • It ensures that the monitored device is held out of operation until internal registers are properly loaded. The reset signal remains asserted until VDD rises above the minimum voltage sense level for time period tPOR. This ensures that the VDD voltage has stabilized. Optional VDD de-coupling capacitance can be added to filter transients if needed. See Figures 13 and 14 illustrating the available evaluation platform, ISL88001/2/3EVAL1Z. This evaluation board is shipped with the many released variants loosely packed and the 4.6V threshold variants mounted for immediate evaluation. • It allows time for an FPGA to download its configuration prior to initialization of the circuit.
