TPS2480PW

Texas Instruments · Supervisor And Reset ICs · TSSOP-20

TPS2480PW from Texas Instruments, in a TSSOP-20. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SDA bidirectional I2C data line for the TPS2480/81 interface, with data input from the I2C bus.
2 SCL input I2C clock input for the TPS2480/81 interface.
3 NC unconnected No internal connection; tie to GND or float.
4 VS power_in Power input to the I2C block, 3.3 V to 5 V, used as the power source for the logic and I2C interface.
5 NC unconnected No connection; tie to GND or float.
6 EN input Device enable input; the GATE driver is enabled only when the positive threshold is exceeded and the internal POR and UVLO thresholds are satisfied.
7 VREF power_in Reference voltage output of 4.0 V used with a resistor divider to set the PROG pin voltage; no more than 1 mA may be drawn.
8 PROG input Power-limit setting input; the applied voltage must stay within 0.4 V to 4.0 V and must not exceed 4 V.
9 TIMER passive Fault timing capacitor pin; the timer charges at 25 mA and discharges at 2.5 mA, and the pin should be tied to ground if the feature is not used.
10 GND power_in System ground.
11 PG output Open-drain power good output that goes high-impedance after the external FET VDS falls to about 1.25 V and a 9-ms deglitch period has elapsed.
12 OUT input Output voltage feedback input used to measure the external FET VDS as V(SENSE-OUT).
13 GATE output High-side gate drive output for the external N-channel FET, with a 22 mA pull-up and a 75 mA (min) pull-down.
14 SENSE input Current-limit sense input monitoring the drain of the external FET and RS; it is internally clamped to VCC, so it must not be driven to a large voltage difference from VCC.
15 VCC power_in Main power supply input to the device and FET; it must exceed the POR (about 6 V) and UVLO (about 8 V) thresholds before normal operation.
16 GND power_in System ground.
17 VINP input Positive differential shunt voltage input, Kelvin connected to the positive side of the current sensing resistor.
18 VINM input Negative differential shunt voltage input, Kelvin connected to the negative side of the current sensing resistor; bus voltage is measured from this pin to GND.
19 A1 input Address pin for setting the I2C address, tied to GND, SDA, SCL or VS as shown in Table 2.
20 A0 input Address pin for setting the I2C address, tied to GND, SDA, SCL or VS as shown in Table 2.
