3 / 82 page  Datasheet 3 Rev. 1.0 2017-11-23 TLE75602-ESH SPIDER+ 12V Overview Description The TLE75602-ESH is an eight channel low-side and high-side power switch in PG-TSDSO-24-21 package providing embedded protective functions. It is specially designed to control relays and LEDs in automotive and industrial applications. A serial peripheral interface (SPI) is utilized for control and diagnosis of the loads as well as of the device. For direct control and PWM there are two input pins available connected to two outputs by default. Additional or different outputs can be controlled by the same input pins (programmable via SPI). Detailed Description The TLE75602-ESH is an eight channel low-side and high-side switch providing embedded protective functions. The output stages incorporate two low-side and six auto-configurable high-side or low side switches (typical RDS(ON) at TJ = 25°C is 1 Ω). The auto-configurable switches can be utilized in high-side or low- side configuration just by connecting the load accordingly. Protection and diagnosis functions adjust automatically to the hardware configuration. Driving a load from high-side offers the possibility to perform Open Load at ON diagnosis. The 16-bit serial peripheral interface (SPI) is utilized to control and diagnose the device and the loads. The SPI interface provides daisy chain capability in order to assemble multiple devices (also devices with 8 bit SPI) in one SPI chain by using the same number of microcontroller pins. This device is designed for low supply voltage operation, therefore being able to keep its state at low battery voltage (VS ≥ 3.0 V). The SPI functionality, including the possibility to program the device, is available only when the digital power supply is present (see Chapter 6 for more details). The TLE75602-ESH is equipped with two input pins that are connected to two configurable outputs, making them controllable even when the digital supply voltage is not available. With the Input Mapping functionality it is possible to connect the input pins to different outputs, or assign more outputs to the same input pin. In this case more channels can be controlled with one signal applied to one input pin. In Limp Home mode (Fail-Safe mode) the input pins are directly routed to channels 2 and 3. When IDLE pin is “low”, it is possible to activate the two channels using the input pins independently from the presence of the digital supply voltage. The device provides diagnosis of the load via Open Load at ON state, Open Load at OFF state (with DIAG_OSM.OUTn bits) and short circuit detection. For Open Load at OFF state detection, a internal current source IOL can be activated via SPI.
