9.1 Application Information

The TPSI2072-Q1 is a two channel 600-V, 50-mA automotive isolated switch optimized for high voltage switching in measurement applications, especially those that require switching across an isolation barrier or galvanically isolated domain. Common end equipments include energy storage systems (ESS), solar panel arrays, EV chargers, and EV battery management systems. The device enables the system designer to reduce cost and improve reliability by replacing mechanical relays and optically isolated devices.

The TPSI2072-Q1's enable inputs are fail safe and do not need to be driven from the same domain as the VDD pin supply.

The TPSI2072-Q1 supports an input voltage range of 4.5 V to 20 V on the VDD primary supply pin and a logic high of 2.1 V to 20 V on the enable pins. The secondary side supports high voltage switching from –600 V to 600V.
