ISL88016, ISL88017 Data Sheet December 22, 2006 FN6141.0 6-Pin Voltage Supervisors with Pin- Features Selectable Voltage Trip Points Pin-Selectable Single Voltage Monitoring Supervisors The ISL88016, ISL88017 supervisors offer pin-selectable User Pin-Selectable Voltage Trip Points voltage trip points along with popular functions such as - ISL88016: 1.60V to 2.85V in 50mV Steps Power-on Reset control, Supply Voltage Supervision, and - ISL88017: 2.15V to 4.65V in 100mV Steps Manual Reset assertion in a small 6 Ld TSOT-23 package. Reduce Inventory on Fixed Voltage Trip Point Options By connecting the three VSET pins to V , GND or floating, DD users can program the voltage trip point from 1.60V to 2.85V Manual Reset Capability in 50mV increments on the ISL88016 and from 2.15V to Proprietary TwinPin Combines Active-Low Reset Output 4.65V in 100mV increments on the ISL88017. These user- and Manual Reset Input Functions into One Pin selectable reset threshold voltages are accurate to 2% over Reset Signal Valid Down to V = 0.8V DD temperature and the reset signal is valid down to 1V. Voltage Threshold 2% Accuracy Over Temp Intersils proprietary TwinPin combines the active low reset out with the manual reset input into one pin. This provides No External Components Necessary device adjustability without sacrificing functionality. These Immune to Power-Supply Transients parts are specifically designed for low power consumption Ultra Low 3A Supply Current and high threshold accuracy.

The V pin is the IC power supply terminal and also the DD DD monitored input. The voltage at this pin is compared against the programmed voltage trip point, V . TP 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 V falls below V . The device is designed DD TH with hysteresis to help prevent chattering due to noise and is immune to brief power-supply transients. 2 GND Ground. 3 VSET1 Voltage Trip Point Select Pins 1, 2 and 3. These inputs are either tied either to GND or V or left DD floating in various combinations to program the falling voltage trip point. See Voltage Trip Point Setting 4 VSET2 Table on following page for programming configurations. 5 VSET3 6 RST/MR Proprietary TwinPin technology combines Active-Low Reset Output and Manual Reset Input Functions into one pin. This dual function pin functions as both the reset output and a manual reset input. The RST output pin has an integrated 100k pull-up resistor to V that is pulled to GND (LOW) DD when reset is asserted, V < programmed voltage trip point. The MR input is an active-low DD debounced input to which a user can connect a push-button to add manual reset capability. FN6141.0 2 December 22, 2006
