ZHCSP56 September 2023 TPS1HTC30-Q1
PRODUCTION DATA
TPS1HTC30-Q1 is designed to provide an enhanced set of diagnostic and protection features. However, if the system design only allows for a limited number of I/O connections, some pins can be considered as optional.
| PIN NAME | CONNECTION IF NOT USED | IMPACT IF NOT USED |
|---|---|---|
| SNS | Ground through 1-kΩ resistor | Analog sense is not available. |
| LATCH | Float or ground through RPROT resistor | With LATCH unused, the device performs an auto-retry after a fault. If latched behavior is desired, but the system describes limited I/O, it is possible to use one microcontroller output to control the latch function of several high-side channels. |
| ILIM | Float | If the ILIM pin is left floating, the device is set to the default internal current-limit threshold. This is considered a fault state for the device. |
| FAULT | Float | If the FAULT pin is unused, the system cannot read faults from the output. |
| DIAG_EN | Float or ground through RPROT resistor | With DIAG_EN unused, the analog sense, open-load, and short-to-battery diagnostics are not available. |
