NAME TPS16630 TPS16632
VQFN HTSSOP VQFN
IN 1 1 1 P Power input. Connects to the DRAIN of the internal FET.
2 2 2
— 3 —
P_IN 5 6 5 P Supply voltage of the device. Always connect P_IN to IN directly.
UVLO 6 7 6 I Input for setting the programmable undervoltage lockout threshold. An undervoltage event turns off the internal FET and asserts FLT to indicate the power-failure.
OVP 7 8 — I Input for setting the adjustable overvoltage protection threshold (for TPS16630 only). An overvoltage event turns off the internal FET and asserts FLT to indicate the overvoltage fault.
PLIM — — 7 I Input for setting the adjustable output power limiting threshold (TPS16632 Only). Connect a resistor across PLIM to GND to set the output power limit. Connect PLIM to GND if PLIM feature is not used. See Output Power Limiting, PLIM (TPS16632 Only) section.
GND 8 9 8 — Connect GND to system ground.
dVdT 9 10 9 I/O A capacitor from this pin to GND sets output voltage slew rate. Leaving this pin floating enables device power up in thermal regulation resulting in fast output charge. See the Hot Pug-In and In-Rush Current Control section.
ILIM 10 11 10 I/O A resistor from this pin to GND sets the overload limit. See Overload and Short Circuit Protection section.
MODE 11 12 11 I Mode selection pin for Overload fault response. See the Device Functional Modes section.
SHDN 12 13 12 I Shutdown pin. Pulling SHDN low makes the device to enter into low power shutdown mode. Cycling SHDN pin voltage resets the device that has latched off due to a fault condition.
IMON 13 14 13 O Analog current monitor output. This pin sources a scaled down ratio of current through the internal FET. A resistor from this pin to GND converts current to proportional voltage. If unused, leave it floating.
FLT 14 15 14 O Fault event indicator. This pin is an open drain output. If unused, leave floating or connect to GND.
PGOOD 16 16 16 O Active High. A high indicates that the internal FET is enhanced. PGOOD goes low when the internal FET is turned OFF during a fault or when SHDN is pulled low. If PGOOD is unused, then connect to GND or leave it floating.
OUT 17 18 17 P Power output of the device.

PowerPAD™ — Connect PowerPAD to GND plane for heat sinking. Do not use PowerPAD as the only electrical connection to GND.
