VNH7070ASTR from STMicroelectronics, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GNDA power_in Ground reference for low-side switch A power stage.
2 OUTA output High-side switch A source / low-side switch A drain output; 15 A maximum continuous output current per Table 1.
3 INA input Clockwise motor direction control input; CMOS logic compatible with 0.9 V low, 2.1 V high threshold per Table 7.
4 VCC power_in Positive power supply; 4 V to 28 V operating range, 40 V maximum transient voltage per Table 4.
5 VCC power_in Positive power supply; 4 V to 28 V operating range, 40 V maximum transient voltage per Table 4.
6 INB input Counter-clockwise motor direction control input; CMOS logic compatible with 0.9 V low, 2.1 V high threshold per Table 7.
7 OUTB output High-side switch B source / low-side switch B drain output; 15 A maximum continuous output current per Table 1.
8 GNDB power_in Ground reference for low-side switch B power stage.
9 GNDB power_in Ground reference for low-side switch B power stage.
10 OUTB output High-side switch B source / low-side switch B drain output; 15 A maximum continuous output current per Table 1.
11 PWM input Voltage-controlled speed modulation input with hysteresis; CMOS compatible, gates low-side FETs during on-phase, 20 kHz maximum frequency per Table 8.
12 VCC power_in Positive power supply; 4 V to 28 V operating range, 40 V maximum transient voltage per Table 4.
13 CS output Multiplexed current sense output pin; delivers current proportional to motor output current, saturation 4.6 mA typical per Table 10.
14 SEL0 input Channel select input; 3 V and 5 V CMOS compatible, addresses current sense output along with INA and INB per operative truth table.
15 OUTA output High-side switch A source / low-side switch A drain output; 15 A maximum continuous output current per Table 1.
16 GNDA power_in Ground reference for low-side switch A power stage.
