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 V
DD
pin is the power supply terminal. The voltage at this
pin is compared against an internal factory-programmed
voltage trip point, V
THVDD
. 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
DD
falls below V
THVDD
. The device is designed with
hysteresis to help prevent chattering due to noise.
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
SC-70 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 V
DD
. The
device asserts a 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 V
DD
exceeds the voltage threshold
setting for the reset time delay period t
POR
. See Figure 2.
