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 | Vbb | power_in | Positive power supply voltage (Vbb), operating range 7.0 to 58 V. Multiple Vbb pins (1, 7, 8, 14) share the leadframe; wire for max simultaneous short-circuit currents from both channels and low thermal resistance. |+| 2 | IN1 | input | Input for channel 1: activates channel 1 on logic-high signal. CMOS-compatible, ground-referenced with integrated 20 kΩ input series resistor. Absolute max input voltage ±42 V DC; max input current ±2.0 mA DC. |+| 3 | ST1 | output | Diagnostic feedback for channel 1: open-drain status output. Integrated pull-up via SPU pin; reports open-load (OFF state) and thermal shutdown (ON state). Max status current ±2.0 mA DC. |+| 4 | GND | power_in | Logic ground. Independent from load ground. External current-limit resistor (150 Ω recommended) advised for Vbb > Vbb(AZ). |+| 5 | ST2 | output | Diagnostic feedback for channel 2: open-drain status output. Integrated pull-up via SPU pin; reports open-load (OFF state) and thermal shutdown (ON state). Max status current ±2.0 mA DC. |+| 6 | IN2 | input | Input for channel 2: activates channel 2 on logic-high signal. CMOS-compatible, ground-referenced with integrated 20 kΩ input series resistor. Absolute max input voltage ±42 V DC; max input current ±2.0 mA DC. |+| 7 | Vbb | power_in | Positive power supply voltage (Vbb), operating range 7.0 to 58 V. Shares leadframe with pins 1, 8, 14. |+| 8 | Vbb | power_in | Positive power supply voltage (Vbb), operating range 7.0 to 58 V. Shares leadframe with pins 1, 7, 14. |+| 9 | OUT2 | power_out | Protected high-side power output of channel 2. On-state resistance ~90 mΩ typ (each channel, Tj=25°C); nominal load current 2.9 A (one channel active); current limitation 8 A. Pins 9 and 10 must be connected in parallel for spec operation. |+| 10 | OUT2 | power_out | Protected high-side power output of channel 2 (parallel with pin 9). Must be tied to pin 9. |+| 11 | SPU | input | Status Pull-Up: connection for external pull-up voltage source (max ±42 V DC) for the open-drain ST1/ST2 status outputs. Pull-up resistors (~12 kΩ / 850 Ω network) are integrated internally. |+| 12 | OUT1 | power_out | Protected high-side power output of channel 1. On-state resistance ~90 mΩ typ (each channel, Tj=25°C); nominal load current 2.9 A (one channel active); current limitation 8 A. Pins 12 and 13 must be connected in parallel for spec operation. |+| 13 | OUT1 | power_out | Protected high-side power output of channel 1 (parallel with pin 12). Must be tied to pin 12. |+| 14 | Vbb | power_in | Positive power supply voltage (Vbb), operating range 7.0 to 58 V.
