The APL6535 is a two channel supervisory IC designed
to monitor voltage supplies in mP 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 out-
put is pulled low, the hysteresis of the internal refer-
ence is 15mV. The PGOOD pin has an internal 20kW
pull-up to V
CC
making an external pull-up resistor
unnecessary. Each rail’s VMON point is independently
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 transient glitches
30ms on VMON input. The PGOOD output 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
CC
. The ENABLE input pin provides
for a reset of the PGOOD output when it is pulled
down below 0.5V. With an internal 10mA pull-up to
VCC, it can be signaled with common logic or pulled
to ground with a push button switch. APL6535 come
in a miniature SOT-23-5 package.
