Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN1A | input | Bridge A logic input 1, TTL/CMOS compatible (turn-on threshold 1.8V typ, turn-off 1.3V typ). |
| 2 | IN2A | input | Bridge A logic input 2, TTL/CMOS compatible (turn-on threshold 1.8V typ, turn-off 1.3V typ). |
| 3 | SENSEA | passive | Bridge A source pin, which must be connected to power ground directly or through a sensing power resistor (voltage range -1 to +4V absolute max). |
| 4 | OUT1A | output | Bridge A output 1, with 2.8A RMS output current capability. |
| 5 | GND | power_in | Signal ground terminal, also used for heat dissipation toward the PCB in the PowerDIP package. |
| 6 | GND | power_in | Signal ground terminal, also used for heat dissipation toward the PCB in the PowerDIP package. |
| 7 | OUT1B | output | Bridge B output 1, with 2.8A RMS output current capability. |
| 8 | SENSEB | passive | Bridge B source pin, which must be connected to power ground directly or through a sensing power resistor (voltage range -1 to +4V absolute max). |

| 10 | IN2B | input | Bridge B logic input 2, TTL/CMOS compatible (turn-on threshold 1.8V typ, turn-off 1.3V typ). |
| 11 | ENB | bidirectional | Bridge B enable: LOW switches OFF all Bridge B power MOSFETs; also the overcurrent/thermal protection open-drain output, so drive through a series resistor of 2.2kΩ-180kΩ (100kΩ recommended), or tie to +5V through a resistor if unused. |
| 12 | VBOOT | passive | Bootstrap voltage needed to drive the upper PowerMOSFETs of both Bridge A and Bridge B (max VS + 10V). |
| 13 | OUT2B | output | Bridge B output 2, with 2.8A RMS output current capability. |
| 14 | VSB | power_in | Bridge B power supply voltage (8 to 52V operating), which must be connected to the supply voltage together with pin VSA. |
| 15 | GND | power_in | Signal ground terminal, also used for heat dissipation toward the PCB in the PowerDIP package. |
| 16 | GND | power_in | Signal ground terminal, also used for heat dissipation toward the PCB in the PowerDIP package. |
| 17 | VSA | power_in | Bridge A power supply voltage (8 to 52V operating), which must be connected to the supply voltage together with pin VSB. |
| 18 | OUT2A | output | Bridge A output 2, with 2.8A RMS output current capability. |
| 19 | VCP | output | Charge pump oscillator output, a 600kHz (typ) square wave with 10V amplitude. |
| 20 | ENA | bidirectional | Bridge A enable: LOW switches OFF all Bridge A power MOSFETs; also the overcurrent/thermal protection open-drain output, so drive through a series resistor of 2.2kΩ-180kΩ (100kΩ recommended), or tie to +5V through a resistor if unused. |
