PRODUCTION DATA
The digital signals have a debounce filtering. The signal/supply is sampled with a clock signal and a counter. This results as an accuracy of one clock period for the debounce window.
| EVENT | SIGNAL/SUPPLY | RISING EDGE DEBOUNCE TIME | FALLING EDGE DEBOUNCE TIME |
|---|---|---|---|
| Enable and disable for BUCKx | EN1 | 3 μs (1) | 3 μs (1) |
| Enable and disable for BUCKx | EN2 | 3 μs (1) | 3 μs (1) |
| Enable and disable for BUCKx | EN3 | 3 μs (1) | 3 μs (1) |
| VANA UVLO | VANA | 20 μs (VANA voltage rising) | Immediate (VANA voltage falling) |
| VANA overvoltage | VANA | 20 μs (VANA voltage rising) | 20 μs (VANA voltage falling) |
