TPS650061RUKR

Texas Instruments · Battery Management · WQFN-20-EP(3x3)

TPS650061RUKR from Texas Instruments, in a WQFN-20-EP(3x3). 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 MR input Active-low input to force a reset; external pull-up required.
2 TRST bidirectional Capacitor connection for setting reset time.
3 EN_LDO1 input Enable input for LDO1 regulator.
4 EN_LDO2 input Enable input for LDO2 regulator.
5 PG output Open-drain active-low power good output.
6 PGND power_in Power ground connected to the thermal pad.
7 SW output Switch pin for DC-DC converter inductor connection.
8 VINDCDC power_in Input voltage supply for DC-DC converter and control blocks, 2.3 V to 6 V range.
9 MODE input Selects force PWM or PWM/PFM automatic-transition mode.
10 EN_DCDC input Enable input for DC-DC converter.
11 FB_DCDC input Feedback voltage input to DC-DC error amplifier.
12 AGND power_in Analog ground; route back to PGND as close to IC as possible.
13 FB_LDO1 input Feedback voltage input to LDO1 error amplifier.
14 VLDO1 output Output voltage from LDO1 regulator, 300 mA maximum.
15 VINLDO1 power_in Input voltage supply for LDO1, 1.6 V to 6 V range.
16 FB_LDO2 input Feedback voltage input to LDO2 error amplifier.
17 VLDO2 output Output voltage from LDO2 regulator, 300 mA maximum.
18 VINLDO2 power_in Input voltage supply for LDO2, 1.6 V to 6 V range.
19 RSTSNS input Voltage input sense pin for reset signal generation.
20 RST output Open-drain active-low reset output.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
