Pin Functions
NAME
NO.
I/O
DESCRIPTION
DEVSLP
1
I
Active High. DevSleep Mode control. A high at this pin will activate the DevSleep mode(Low Power Mode).
PGOOD
2
O
Active High. A high indicates PGTH has crossed the threshold value. It is an open drain output.
PGTH
3
I
Positive input of PGOOD comparator.
OUT
4 - 8
O
Power Output of the device.
IN
9 - 13
I
Power Input and supply voltage of the device.
Input for setting programmable undervoltage lockout threshold. An undervoltage event will open internal FET and assert
EN/UVLO
14
I
FLT to indicate power-failure. When pulled to GND, resets the fault latch in TPS25940L.
Input for setting programmable overvoltage protection threshold. An overvoltage event will open the internal FET and
OVP
15
I
assert FLT to indicate overvoltage.
GND
16
Ground.
ILIM
17
I/O
A resistor from this pin to GND sets the overload and short-circuit current limit.
dVdT
18
I/O
A capacitor from this pin to GND sets the ramp rate of output voltage.
This pin sources a scaled down ratio of current through the internal FET. A resistor from this pin to GND converts current
IMON
19
O
to proportional voltage, used as analog current monitor.
Fault event indicator, goes low to indicate fault condition due to Undervoltage, Overvoltage, Reverse voltage and Thermal
FLT
20
O
shutdown event. It is an open drain output.
The GND terminal must be connected to the exposed PowerPAD. This PowerPAD must be connected to a PCB ground
PowerPADTM
plane using multiple vias for good thermal performance.
