TLE7231G Datasheet PDF - Infineon

●The TLE7231G is a 4-channel low-side SPI Driver for enhanced relay control providing embedded protective function. The 8-bit serial peripheral interface (SPI) is provided for control and diagnostics of the device and the loads and also for daisy-chain capability. This 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.

● Very wide range for digital supply voltage

● An input pin provides flexible and straight forward PWM operation

● Stable behaviour at under-voltage

● Less microcontroller I/Os needed

● Protection of load and device

● Reduced PCB space

● Improved reliability

● Less external components
