TPS24770RGET

Texas Instruments · Supervisor And Reset ICs · VQFN-24-EP(4x4)

TPS24770RGET from Texas Instruments, in a VQFN-24-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No connect. Tie to ground or leave floating.
2 ENHS input Active-high enable input of Hot Swap. Logic input connects to resistor divider.
3 NC unconnected No connect. Tie to ground or leave floating.
4 FLTb output Active-low, open-drain output indicating various faults.
5 PGHS output Active-high, open-drain power-good indicator.
6 NC unconnected No connect. Tie to ground or leave floating.
7 TINR bidirectional Inrush timer, which runs during the inrush operation (start-up) if the part is in current limit or power limit.
8 TFLT bidirectional Fault timer, which runs when the device is in regular operation and there is an overcurrent condition.
9 OV input Overvoltage comparator input connects to resistor divider; HGATE pulled low when OV exceeds threshold or connect to ground when not used.
10 GND power_in Ground.
11 PLIM input Power limit programming pin; resistor from this pin to GND sets maximum power dissipation for Hot Swap FET, or connect 4.99 kΩ resistor to disable power limit.
12 IMON bidirectional Analog monitor and current limit program point; connect RIMON to ground.
13 IMONBUF output Voltage output proportional to the load current with range 0V-3.0V.
14 VDD power_in Power Supply input, 2.5V to 18V.
15 SET input Current-limit programming set pin for Hot Swap; resistor connected from positive terminal of the sensing resistor.
16 FSTP input Fast trip programming set pin for Hot Swap; resistor connected from positive terminal of RSNS to FSTP.
17 SENM input Current-sensing input for the sense resistor; directly connects to the negative terminal of the sense resistor.
18 HGATE output Gate driver output for external Hot Swap MOSFET.
19 OUTH input Output voltage sensor for monitoring Hot Swap MOSFET's power; connects to the source terminal of the Hot Swap N channel MOSFET.
20 NC unconnected No connect. Tie to ground or leave floating.
21 NC unconnected No connect. Tie to ground or leave floating.
22 NC unconnected No connect. Tie to ground or leave floating.
23 NC unconnected No connect. Tie to ground or leave floating.
24 NC unconnected No connect. Tie to ground or leave floating.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
