Pinouts
The APL6536 is a four channel supervisory IC de-
signed to monitor voltage supplies in µP and digital
system. This IC can supervise any positive voltage
using an external resistor divider to translate to a lower
voltage for comparison to the internal 0.633V reference.
Once any VMON input falls below 0.633V the PGOOD
output is pulled low, the hysteresis of the internal ref-
erence is 15mV. The PGOOD pin has an internal
20kΩ pull-up to VCC making an external pull-up resis-
tor unnecessary. Each rail’s VMON point is indepen-
dently adjustable with a resistor divider. The PGOOD
output is guaranteed to be valid with IC bias lower
than 1V. This IC is designed to reject fast line tran-
sient glitches 30µs on VMON input. The PGOOD out-
put is an open-drain to allow ORing of multiple signals.
If less than four voltages are being monitored, connect
the unused VMON pins to V . The ENABLE inputhttp://www.DataSheet4U.com/
CC
pin provides for a reset of the PGOOD output when it
is pulled down below 0.5V. With an internal 10µA
pull-up to VCC, it can be signaled with common logic or
pulled to ground with a push button switch. APL6536
come in a miniature SOP-8 package.
