TPSI3050-Q1 - Texas Instruments

TPSI3050-Q1 Automotive Reinforced Isolated Switch Driver

The TPSI3050-Q1 is a fully integrated, isolated switch driver, which when combined with an external power switch, forms a complete isolated Solid State Relay (SSR). With a nominal gate drive voltage of 10 V with 1.5/3.0-A peak source and sink current, a large variety of external power switches can be chosen to meet a wide range of applications. The TPSI3050-.
