TPS92601QPWPRQ1

Texas Instruments · LED Drivers · HTSSOP-20-EP

TPS92601QPWPRQ1 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 ICTRL1 input LED current-control input for analog dimming of channel 1; recommended range 0 V to 3.3 V, and the internal clamp limits its effect at 1.5 V.
2 COMP1 output Compensation network connection for the channel 1 error amplifier; a single capacitor here sets a dominant pole for loop stability.
3 OVFB1 input Voltage-feedback input for channel 1 from the external output resistor divider; recommended range 0 V to 8 V, absolute maximum 80 V.
4 RT input Oscillator pin and input for external synchronization frequency; recommended range 0 V to 3.3 V.
5 DIAG1 output Channel 1 diagnostic output that signals open LED, short, and LED current as a 0.2 V to 2.85 V analog voltage; absolute maximum 3.6 V.
6 GND power_in Ground reference for the device; all voltages are referenced to this pin.
7 PWMIN1 input PWM input and channel 1 enable/disable; enable/disable range 0 V to 40 V, PWM functionality range 0 V to 7 V.
8 VIN power_in Supply voltage input; absolute maximum 40 V, with 6 V to 26 V specified for full functionality on first battery connection.
9 NC unconnected No internal connection.
10 NC unconnected No internal connection.
11 NC unconnected No internal connection.
12 NC unconnected No internal connection.
13 VCC power_out Gate-drive supply voltage that requires an external decoupling capacitor; recommended range 3 V to 8 V, absolute maximum 8.8 V.
14 GDRV1 output Gate driver output for the channel 1 external low-side NMOS boost FET; absolute maximum range -0.3 V to 8.8 V.
15 ISNS1 input Overcurrent sense input for channel 1; recommended range 0 V to 8 V.
16 PGND1 power_in Power ground for channel 1, which should be connected to the thermal pad.
17 ISP1 input Positive current-sense input for channel 1 across the high-side LED shunt; recommended common-mode range 4 V to 75 V.
18 ISN1 input Negative current-sense input for channel 1 across the high-side LED shunt; recommended common-mode range 4 V to 75 V.
19 VOUT1 input Connection to the boost output voltage for channel 1 used for output sensing; recommended range 4 V to 75 V, absolute maximum 80 V.
20 PWMO1 output Gate driver output for the channel 1 high-side PWM-dimming PMOS FET; absolute maximum 80 V.
21 Thermal pad passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS92601QPWPRQ1
  • 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: tps92601qpwprq1-etched.step / tps92601qpwprq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps92601qpwprq1.step / tps92601qpwprq1.glb are the bare package body.
