Applications Information
Connect to system ground through a resistor. Connect a bypass capacitor
to VEE. The voltage from VCC to VEE is nominally 13V set by an internal
zener diode.
An external resistor divider from the system input voltage sets the under-
voltage turn-on threshold. The enable threshold at the pin is 2.5V above
VEE. An internal 22 µA current source provides hysteresis. This pin can be
used for remote enable and disable.
An external resistor divider from the system input voltage sets the over-
voltage turn-off threshold. The disable threshold at the pin is 2.5V above
VEE. An internal 22 µA current source provides hysteresis.
