TLE7233GXUMA1

TLE 7233G is a four channel low-side relay switch (1Ω per channel) in PG-SSOP-24-5 package providing embedded protective function. It is especially designed as a rely driver for automotive applicants. The 8 bit serial interface (SPI) is provided for control and diagnostics of the device and loads. The SPI interface provides daisy-chain capability The TLE 7233G is equipped with an input pin that can be individually routed to the output control of each channel and therefore offer complete flexibility in design and PCB layout. The input multiplexer is controlled via SPI. The limp home pin (LHI) provides a simple use of the input pins; this enables a direct connection between the input pins and their corresponding outputs. The limp home function works under VDDA in order to ensure functionality even with a missing digital supply.
