Pin Functions

PINS I/O DESCRIPTION
NAME TPS24710/11 TPS24712/13
EN 2 2 I Active-high enable input. Logic input. Connects to resistor divider.
FLT 10 O Active-high, open-drain output indicates overload fault timer has turned MOSFET off.
FLTb 10 Active-low, open-drain output indicates overload fault timer has turned MOSFET off.
GATE 7 7 O Gate driver output for external MOSFET
GND 5 5 Ground
OUT 6 6 I Output voltage sensor for monitoring MOSFET power.
PG 1 O Active-high, open-drain power good indicator. Status is determined by the voltage across the MOSFET.
PGb 1 Active-low, open-drain power good indicator. Status is determined by the voltage across the MOSFET.
PROG 3 3 I Power-limiting programming pin. A resistor from this pin to GND sets the maximum power dissipation for the FET.
SENSE 8 8 I Current sensing input for resistor shunt from VCC to SENSE.
TIMER 4 4 I/O A capacitor connected from this pin to GND provides a fault timing function.
VCC 9 9 I Input-voltage sense and power supply
