TLE75602-ESD

SPIDER+ 12V

Overview

Detailed Description

The TLE75602-ESD 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.

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-ESD 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 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.

Each output stage is protected against short circuit. In case of Overload, the affected channel switches OFF

when the Overload Detection Current IL(OVLn) is reached and can be reactivated via SPI. In Limp Home mode

operation, the channels connected to an input pin set to “high” restart automatically after Output Restart time

tRETRY(LH) is elapsed. Temperature sensors are available for each channel to protect the device against Over

Temperature.

The power transistors are built by N-channel power MOSFET with one central chargepump for auto-

configurable channels. The inputs are ground referenced TTL compatible. The device is monolithically

integrated in Smart Power Technology.
