ZHCSLC3B may 2020 – april 2023 TPD3S713-Q1 , TPD3S713A-Q1
PRODUCTION DATA
The device features an active-low, open-drain fault output. FAULT goes low when there is a fault condition. Fault detection includes overtemperature, overcurrent, or overvoltage on VBUS, DP_IN and DM_IN. Connect a 10-kΩ pullup resistor from FAULT to IN.
Table 8-1 summarizes the conditions that generate a fault and actions taken by the device.
| EVENT | CONDITION | TPD3S713-Q1 | TPD3S713A-Q1 |
|---|---|---|---|
| Overvoltage on the data lines | V(DP_IN) or V(DM_IN) > 3.9 V | The device immediately shuts off the USB data switches and the internal power switch. The fault indicator asserts with a 16-ms deglitch, and deasserts without deglitch. | The device immediately shuts off the USB data switches, and the internal power switch keeps turn on. The fault indicator asserts with a 16-ms deglitch, and deasserts without deglitch. |
| Overvoltage on V(BUS) | V(BUS) > 6 V | The device immediately shuts off the internal power switch and the USB data switches. The fault indicator asserts with a 16-ms deglitch and deasserts without deglitch. | The device immediately shuts off the internal power switch and the USB data switches. The fault indicator asserts with a 16-ms deglitch and deasserts without deglitch. |
| Overcurrent on V(BUS) | I(BUS) > I(OS) | The device regulates switch current at I(OS) until thermal cycling occurs. The fault indicator asserts and deasserts with an 8-ms deglitch. | The device regulates switch current at I(OS) until thermal cycling occurs. The fault indicator asserts and deasserts with an 8-ms deglitch. |
| Overtemperature | TJ > OTSD2 in non-current-limited or TJ > OTSD1 in current-limited mode. | The device immediately shuts off the internal power switch and the USB data switches. The fault indicator asserts immediately when the junction temperature exceeds OTSD2 or OTSD1 while in a current-limiting condition. The device has a thermal hysteresis of 20°C. | The device immediately shuts off the internal power switch and the USB data switches.
