The TPSI3100-Q1 is a fully integrated isolated switch driver, which when combined with an external power switch, forms a complete isolated solid state relay solution. With a gate drive voltage of 15.8-V with 1.5/2.5-A peak source/sink current, a large availability of power switches can be used to meet many application needs. The TPSI3100-Q1 generates its own secondary bias supply from power received on its primary side, so no isolated secondary supply bias is required. The TPSI3100-Q1 provides additional power via the nominal 5-V rail (VDDM) for use by auxiliary circuits to perform various function such as current and voltage monitoring or remote temperature detection. The TPSI3100-Q1 isolation is extremely robust with much higher reliability, lower power consumption, and increased temperature ranges than those found using traditional mechanical relays and optocouplers.
The TPSI3100-Q1 integrates a communication back-channel that transfers status information from the secondary side to the primary side via open-drain outputs, PGOOD (Power Good), FLT1 (Fault 1), and ALM1 (Alarm 1). Dual high-speed comparators with an integrated shared voltage reference are used to assert FLT1 and ALM1. When the comparator input, FLT1_CMP, exceeds the voltage reference, the driver is immediately asserted low and FLT1 is also driven low, indicating to the system that a fault has occurred. This is useful for disabling the external switch with low latency on critical events, such as over-current detection. When the comparator input, ALM1_CMP, exceeds the voltage reference, ALM1 signal is asserted low, but no action is taken by the driver. This may be useful as an alarm or warning indicator for over-temperature or over-voltage events.
The TPSI310xL-Q1 series offers a latch based fault indicator. When a fault is detected, the driver and the fault indicator are asserted low and remain latched, until EN is asserted low. The TPSI310x-Q1 series has a non-latched fault indicator. If the fault event is no longer present, FLT1 deasserts and the driver, after a specified recovery period, follows the state of the EN pin. If the fault event still remains, both the fault indicator and the driver remain asserted low.
