PRODUCTION DATA
TPS22996 integrates a unique architecture for adjusting the rise time. The device senses the current flowing into the ON1 and ON2 (ION) pins and utilizes the information to set the rise time. This allows the user to adjust the rise time by connecting a series resistance that is determined by the ON Pin voltage. Refer to Table 8-1 and Table 8-2 for reference on setting the resistor.
ION | VIN = 0.6 V | VIN = 1.8 V | VIN = 2.5 V | VIN = 3.3 V | VIN = 5.0 V |
---|---|---|---|---|---|
20 μA | 810 μs | 1434 μs | 1760 μs | 1986 μs | 2580 μs |
100 μA | 215 μs | 364 μs | 445 μs | 519 μs | 688 μs |
250 μA | 90 μs | 151 μs | 185 μs | 220 μs | 291 μs |
ION | VIN = 0.6 V | VIN = 1.8 V | VIN = 2.5 V | VIN = 3.3 V |
---|---|---|---|---|
20 μA | 781 μs | 1489 μs | 1821 μs | 2154 μs |
100 μA | 200 μs | 374 μs | 451 μs | 536 μs |
250 μA | 93 μs | 175 μs | 207 μs | 244 μs |
The following equation can be used to estimate the series resistance required to meet the desired rise time.
