Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Device power ground; connect to resistor-diode ground network for reverse battery protection. |
| 2 | EN | input | Digital input control for channel activation; 1.5V logic high threshold with 200-350kΩ internal pulldown. |
| 3 | DIAG_EN | input | Digital input to enable/disable diagnostics; 1.5V logic high threshold with 100-250kΩ internal pulldown. |
| 4 | FAULT | tri_state | Open-drain global fault output; asserts low when overcurrent, thermal shutdown, or other faults detected. |
| 5 | LATCH | input | Digital input to select thermal shutdown recovery mode (latch-off vs auto-retry); 1.5V logic high threshold with 0.5-1.5MΩ internal pulldown. |
| 6 | SNS | output | Analog output proportional to load current with 1/1040 sense ratio; voltage range 0 to VSNSFH (3.15-5V dependent on DIAG_EN). |
| 7 | ILIM | output | Current limit setting pin; connect external resistor RILIM to ground to program current limit (0.69-6.15A) or leave floating for 3A default. |
| 8 | NC | unconnected | No internal connection. |
| 9 | VOUT | power_out | High-side switch output connected to load; maximum continuous current 2.5A at 85°C with 88mΩ on-resistance at 25°C (6V-28V supply). |
| 10 | VOUT | power_out | High-side switch output connected to load; maximum continuous current 2.5A at 85°C with 88mΩ on-resistance at 25°C (6V-28V supply). |
| 11 | NC | unconnected | No internal connection. |
| 12 | VBB | power_in | Power supply input; nominal range 3.5-18V for automotive systems with extended range 2.6-28V; UVLO rising threshold 3.5V, falling 2.6V. |
| 13 | VBB | power_in | Power supply input; nominal range 3.5-18V for automotive systems with extended range 2.6-28V; UVLO rising threshold 3.5V, falling 2.6V. |
| 14 | NC | unconnected | No internal connection. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
