TLE7231GXUMA1

TLE 7231G is a four channel low-side relay switch (1Ω per channel) in PG-DSO-14-1 package providing embedded protective function. It is especially designed as a rely driver for automotive applicants. The 8 bit serial interface (SPI) interface provides daisy-chain capability. The TLE 7231G 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 device provides many diagnostics of the load enabling both open load and short circuit detection. The SPI diagnostic bits indicate any eventual latched fault condition.
