I/O DESCRIPTION DMODE 1 I Diode Mode control pin. A high at this pin will activate the Non-ideal Diode 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. Input for setting programmable undervoltage lockout threshold. An undervoltage event will open EN/UVLO 14 I internal FET and assert FLT to indicate power-failure. When pulled to GND, resets the fault latch in TPS25942L, TPS25944L. Input for setting programmable overvoltage protection threshold. An overvoltage event will open OVP 15 I the internal FET and 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 IMON 19 O to GND converts current to proportional voltage, used as analog current monitor. Fault event indicator, goes low to indicate fault condition due to Undervoltage, Overvoltage, FLT 20 O Reverse voltage, Circuit breaker timeout (TPS25944 only) and Thermal shutdown events. It is an open drain output. The GND terminal must be connected to the exposed PowerPAD. This PowerPAD must be PowerPADTM connected to a PCB ground plane using multiple vias for good thermal performance. 4 Submit Documentation Feedback Copyright © 2014–2015, Texas Instruments Incorporated Product Folder Links: TPS25942A TPS25942L TPS25944A TPS25944L |
