TPS2483PWR

Texas Instruments · Supervisor And Reset ICs · TSSOP-20

TPS2483PWR 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 Serial-bus data line, open-drain input/output; the device supports Fast (1 kHz to 400 kHz) and High-speed (1 kHz to 3.4 MHz) I2C/SMBus modes.
2 SCL input Serial-bus clock line, high-impedance input that serves as the clock input for the serial-bus interface.
3 ALERT output Serial-bus multi-function alert signal, open-drain output that can be programmed to go low when a user-defined threshold has been exceeded.
4 VS power_in Monitor section bias-supply input for POR1, control logic, ADC and serial-bus interface, typically between 2.7 V and 5.5 V.
5 N/C unconnected No connection; tie to GND or float.
6 EN input Hotswap section enable input with hysteresis between its upper and lower thresholds; it can be tied to VCC to always enable the device.
7 VREF power_in Reference voltage output used to set the power-limit threshold on PROG; reference source current is specified as 0 to 1 mA.
8 PROG input Pass-MOSFET power-limit programming input, normally 0.4 V to 4.0 V, with voltages greater than 4 V not to be applied.
9 TIMER input Connect the fault timing capacitor from TIMER to GND; the pin should be tied to ground if the timer feature is not used.
10 GND power_in System ground; common reference for all other input and output voltages.
11 PG output Open-drain power-good output based on VSENSE - VOUT, going high-impedance after pass-MOSFET VDS falls below 1.25 V and a 9-ms deglitch time has elapsed.
12 OUT input Input that senses pass-MOSFET source voltage for power-limit protection and PG determination; if the load can drive OUT below ground, a clamp diode is required to keep VOUT above -0.3 V.
13 GATE output Pass-MOSFET gate-drive output with a 22 µA pull-up from the internal charge pump and a pull-down to ground of at least 75 mA.
14 SENSE input Input that senses pass-MOSFET drain voltage and the downstream side of the current-shunt RS; it should not be driven to a large voltage difference from VCC.
15 VCC power_in Hotswap section bias-supply input and positive reference for current-shunt sensing; it must exceed the POR2 threshold (about 6 V) and UVLO turn-on threshold (about 8.4 V) before GATE is driven, with recommended range 9 V to 80 V.
16 GND power_in System ground; common reference for all other input and output voltages.
17 VINM input Negative differential shunt voltage input, Kelvin-connected to the negative (load) side of the shunt resistor, which also measures bus voltage to GND within the 0 V to 36 V monitor input range.
18 VINP input Positive differential shunt voltage input, Kelvin-connected to the positive (source) side of the shunt resistor.
19 A1 input Serial-bus address input, connected to GND, SCL, SDA or VS to select the slave address per Table 8.
20 A0 input Serial-bus address input, connected to GND, SCL, SDA or VS to select the slave address per Table 8.
