TPS3619-33DGK

Texas Instruments · Supervisor And Reset ICs · VSSOP-8-0.65mm

TPS3619-33DGK from Texas Instruments, in a VSSOP-8-0.65mm. 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 VOUT output Supply output that connects to VDD or VBAT through internal switches, with continuous output current limited to 300 mA under the recommended operating conditions.
2 VDD power_in Input supply voltage, with a recommended operating range of 1.65 V to 5.5 V.
3 GND power_in Ground reference; all voltages in the absolute maximum ratings are specified with respect to GND.
4 PFI input Power-fail comparator input, compared against an internal 1.15 V reference, with input current limited to ±25 nA and a maximum voltage of VDD + 0.3 V.
5 PFO output Power-fail comparator output that goes low when PFI falls below the 1.15 V threshold and returns high after about 12 mV of hysteresis, with a low-level output of 0.4 V maximum at VDD = 3.3 V and IOL = 2 mA.
6 MR input Manual reset input with VIH of 0.7 × VDD and VIL of 0.3 × VDD, and an input transition rise and fall rate limited to 100 ns/V.
7 RESET output Active-low reset output that is asserted while VDD is below the threshold VIT and is released after a fixed 100 ms delay (60 to 140 ms) once VDD rises above VIT.
8 VBAT power_in Backup-battery input with a recommended supply voltage of 1.5 V to 5.5 V, which may exceed VDD.
