TPS26636PWPT

Texas Instruments · Power Management Specialized - PMIC · HTSSOP-20-EP

TPS26636PWPT from Texas Instruments, in a HTSSOP-20-EP. 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 IN power_in Power input that connects to the drain of the internal 31 mΩ FET; IN and IN_SYS are specified for 4.5 V to 60 V operation.
2 IN power_in Power input that connects to the drain of the internal FET; IN and IN_SYS are specified for 4.5 V to 60 V operation.
3 IN power_in Power input (name cell blank in Table 5-1; assigned IN from Figure 5-4 and the pin-count pattern) connecting to the drain of the internal FET; do not leave any IN pin unconnected.
4 B_GATE output Blocking FET gate driver output; connect to the GATE of the external N-channel FET and leave floating if no external FET is used, with B_GATE to IN_SYS limited to 14 V.
5 DRV output Blocking FET fast pulldown switch drive; connect to the GATE of the external pulldown switch and leave floating if no external N-FET is used, with DRV to IN_SYS limited to 20 V.
6 IN_SYS power_in Power input and supply voltage of the device; connect to the source of the blocking FET when used, or short to IN if no blocking FET is used, with a minimum 0.1 µF capacitor across IN_SYS and GND.
7 UVLO input Input for the programmable undervoltage lockout threshold; an undervoltage event turns off the internal FET and asserts FLT, and connecting UVLO to GND selects the internal default threshold.
8 PLIM input Input for the programmable output power limit on TPS26636 (PLIM replaces OVP on this variant); connect a resistor from PLIM to GND to set the limit, or connect PLIM directly to GND to disable the feature.
9 GND power_in Connect to system ground; the PowerPAD must also be tied to the GND plane for heat sinking and must not be the only GND connection.
10 dVdT bidirectional A capacitor from this pin to GND sets the output voltage slew rate during hot plug-in and inrush control.
11 ILIM bidirectional A resistor from this pin to GND sets the overload and short-circuit current limit, with ILIM resistance specified from 3 kΩ to 30 kΩ; the FET turns off if ILIM is shorted or open to GND.
12 MODE input Mode selection pin for overload fault response (auto-retry or latch-off), with a recommended operating range of 0 V to 4 V.
13 SHDN input Shutdown pin; pulling it below 0.8 V enters low-power shutdown, cycling it resets a latched-off device, and it must be pulled up to at least 2 V to enable the device, with a recommended range of 0 V to 5 V.
14 IMON output Analog current monitor output that sources a current proportional to load current (27.9 µA/A typical) and must not exceed 4 V when converted by a resistor to GND; leave floating if unused and do not add a bypass capacitor.
15 FLT output Open-drain active-low fault indicator for undervoltage, overvoltage, overload, power limiting, reverse current, ILIM short and thermal shutdown; leave floating or connect to GND if unused, with a recommended range of 0 V to 60 V.
16 PGTH input PGOOD comparator input; PGOOD goes high when PGTH crosses the V(PGTHR) threshold, with an absolute maximum of 67 V.
17 PGOOD output Active-high power-good output that goes low when PGTH falls to V(PGTHF), with a maximum sink current of 10 mA; connect to GND or leave floating if unused.
18 OUT power_out Power output of the device, specified for 0 V to 60 V at the recommended operating conditions; do not leave OUT pins unconnected.
19 OUT power_out Power output of the device, specified for 0 V to 60 V at the recommended operating conditions; do not leave OUT pins unconnected.
20 OUT power_out Power output of the device (name cell blank in Table 5-1; assigned OUT from Figure 5-4 and the pin-count pattern); do not leave OUT pins unconnected.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS26636PWPT
  • Footprint: Package_SO:TSSOP-20-1EP_4.4x6.5mm_P0.65mm_EP2.15x3.35mm
  • 3D model: HTSSOP-20-EP, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.2 mm nominal TSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: tps26636pwpt-etched.step / tps26636pwpt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps26636pwpt.step / tps26636pwpt.glb are the bare package body.
