DRV411AIPWPR

Texas Instruments · ADC/DAC - Specialized · HTSSOP-20-EP

DRV411AIPWPR 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 REFSEL1 input Input that sets the reference mode together with REFSEL2 (see the Voltage Reference section); CMOS logic levels, VIH 0.7×VDD min and VIL 0.3×VDD max.
2 REFOUT output Output terminal for the selected reference voltage (2.5 V, 1.65 V, or ratiometric 50% of VDD); load regulation 0.15-0.35 mV/mA.
3 REFIN input Input for the zero reference to the differential amplifier.
4 VOUT output Output of the differential amplifier.
5 IAIN2 input Noninverting input of the differential amplifier; inputs must be limited to 5 mA (max) or ±1.5 V (max).
6 IAIN1 input Inverting input of the differential amplifier; inputs must be limited to 5 mA (max) or ±1.5 V (max).
7 GND power_in Ground connection.
8 GND power_in Ground connection.
9 ICOMP2 output Output 2 of the compensation coil driver (250 mA H-bridge; ICOMP short-circuit limit 300 mA).
10 ICOMP1 output Output 1 of the compensation coil driver (250 mA H-bridge; ICOMP short-circuit limit 300 mA).
11 VDD power_in Supply voltage, specified from 2.7 V to 5.5 V (absolute maximum 7 V).
12 GSEL2 input Input that selects the gain of the Hall amplifier together with GSEL1 (see Gain Selection and Compensation Frequency section); CMOS logic levels.
13 GSEL1 input Input that selects the gain of the Hall amplifier together with GSEL2 (see Gain Selection and Compensation Frequency section); CMOS logic levels.
14 ERROR output Open-drain error indication output with no internal pull-up; requires an external pull-up resistor (see the Error Conditions section).
15 HALL4 passive Pin 4 of an AKM HW322 / HW302 or similar Hall element.
16 HALL3 passive Pin 3 of an AKM HW322 / HW302 or similar Hall element.
17 HALL2 passive Pin 2 of an AKM HW322 / HW302 or similar Hall element.
18 HALL1 passive Pin 1 of an AKM HW322 / HW302 or similar Hall element.
19 OR output Open-drain overrange indication output with no internal pull-up; requires an external pull-up resistor (see the Error Conditions section).
20 REFSEL2 input Input that sets the reference mode together with REFSEL1 (see the Voltage Reference section); CMOS logic levels.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: DRV411AIPWPR
  • 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: drv411aipwpr-etched.step / drv411aipwpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); drv411aipwpr.step / drv411aipwpr.glb are the bare package body.
