9.1 Application Information

The TPSI2260-Q1 is a 600V, 50mA 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 TPSI2260-Q1's enable input is fail safe and does not need to be driven from the same domain as the VDD pin supply.

The TPSI2260-Q1 supports an input voltage range from 4.5V to 20V on the VDD primary supply pin and a logic high from 2.1V to 20V on the enable pin. The secondary side supports high voltage switching from –600V to 600V.
