DETAILED OPERATION
Turn On Delay
The turn on delay prohibits the output switches from being
turned on for a period of time after V
CC
has passed through
8 V and the undervoltage condition no longer exists. The
UVLO function keeps the external C
DEL
capacitor discharged
until V
CC
is greater than 8 V. Subsequently, an internal 2.5-mA
current source charges the capacitor from GND to 4.7 V. A
comparator detects when the voltage on C
DEL
passes
through 4 V and enables the output switches. The delay time
is a function of the capacitor value and is defined as
1.6 ms/nF.
An external switch can be connected across the capacitor to
disable the output switches and reset the time delay.
Short Circuit and Overcurrent indication
When an overcurrent or short circuit condition occurs on
either switch, the SiP43101 enters a hiccup current limiting
mode. In this mode, the capacitor on C
DEL
is discharged
down to 3 V, thus turning off the output switches, and then is
charged up to 4 V by a 2.5-mA internal current source, thus
turning the switches on again. If the overcurrent or short circuit
condition remains this cycle will continue. The switches are
enabled at a very low duty cycle, minimizing the power
dissipation and protecting the switches from damage.
The FAULT output will switch to GND, indicating that an
overload condition or short circuit condition exists.
