Data Sheet
6-Pin Voltage Supervisors with Pin-
Selectable Voltage Trip Points
The ISL88016, ISL88017 supervisors offer pin-selectable
voltage trip points along with popular functions such as
Power-on Reset control, Supply Voltage Supervision, and
Manual Reset assertion in a small 6 Ld TSOT-23 package.
By connecting the three VSET pins to V
users can program the voltage trip point from 1.60V to 2.85V
in 50mV increments on the ISL88016 and from 2.15V to
4.65V in 100mV increments on the ISL88017. These user-
selectable reset threshold voltages are accurate to ±2% over
temperature and the reset signal is valid down to 1V.
Intersil’s proprietary TwinPin™ combines the active low reset
out with the manual reset input into one pin. This provides
device adjustability without sacrificing functionality. These
parts are specifically designed for low power consumption
and high threshold accuracy.
