TPSI2140-Q1Automotive 1200-V 50-mA isolated switch with 2-mA avalanche rating | Solid State Relays (SSR) | 1 | Active | The TPSI2140-Q1 is an isolated solid state relay designed for high voltage automotive and industrial applications. The TPSI2140-Q1 uses TI’s high reliability capacitive isolation technology in combination with internal back-to-back MOSFETs to form a completely integrated solution requiring no secondary side power supply.
The primary side of the device is powered by only 9 mA of input current and incorporates a fail-safe EN pin preventing any possibility of back powering the VDD supply. In most applications, the VDD pin of the device should be connected to a system supply between 5 V–20 V and the EN pin of the device should be driven by a GPIO output with logic HI between 2.1 V–20 V. In other applications, The VDD and EN pins could be driven together directly from the system supply or from a GPIO output. All control configurations of the TPSI2140-Q1 do not require additional external components such as a resistor and/or low side switch that are typically required in photo relay solutions.
The secondary side consists of back-to-back MOSFETs with a standoff voltage of ±1.2 kV from S1 to S2. The TPSI2140-Q1 MOSFET’s avalanche robustness and thermally conscious package design allow it to robustly support system level dielectric withstand testing (HiPot) and DC fast charger surge currents of up to 2 mA without requiring any external components.

TPSI3100Isolated switch driver with 17V gate supply and dual isolated comparators | Isolators | 1 | Active | The TPSI3100 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 17V with 1.5A and 2.5A peak source and sink current, a large availability of power switches can be used to meet many application needs. The TPSI3100 generates its own secondary bias supply from power received on its primary side, so no isolated secondary supply bias is required. The TPSI3100 provides additional power via the nominal 5V rail (VDDM) for use by auxiliary circuits to perform various function such as current and voltage monitoring or remote temperature detection. The TPSI3100 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 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 overcurrent 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 overtemperature or overvoltage events.
The TPSI310xL 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 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.
