Infineon TLE8110EE

10-channel Low-Side Switch in Smart Power Technology [SPT] with Serial Peripheral Interface [SPI] and 10 open drain DMOS output stages. The TLE8110EE is protected by embedded protection functions and designed for automotive and industrial applications. The output stages are controlled via Parallel Input Pins for PWM use or SPI Interface. The TLE8110EE is particularly suitable for Engine Management and Powertrain Systems.

The TLE8110EE is a 10-channel low-side switch in PG-DSO-36 package providing embedded protection functions. The 16-bit serial peripheral interface (SPI) can be utilized for control and diagnosis of the device and the loads. The SPI interface provides daisy-chain capability in order to assemble multiple devices in one SPI chain by using the same number of micro-controller pins.

The analogue and the digital part of the device is supplied by 5V. Logic Input and Output Signals are then compatible to 5V logic level [TTL - level]. Optionally, the logic part can be supplied with lower voltages to achieve signal compatibility with e.g. 3.3V logic level [CMOS - level].

The TLE8110EE is equipped with 10 parallel input pins that are routed to each output channel. This allows control of the channels for loads driven by Pulse Width Modulation (PWM). The output channels can also be controlled by SPI.

The device is equipped with one Reset Pin and one Enable. Reset [RST] serves the whole device, Enable [EN] serves only the Output Control Unit and the Power Stages.

The device provides diagnosis of the load, including open load, short to GND as well as short circuit to V_Batt detection and over-load / over-temperature indication. The SPI diagnosis flags indicates if latched fault conditions may have occurred.

Each output stage is protected against short circuit. In case of over load, the affected channel is switched off. The switching off reaction time is dependent on two switching thresholds. Restart of the channel is done by clearing the Diagnosis Register. This feature protects the device against uncontrolled repetitive short circuits. The reaction to a short-circuit and over-temperature can be alternatively changed to further modes, such as semi- or auto - restart of the affected channel.

There is a temperature sensor available for each channel to protect the device in case of over temperature. In case of over temperature the affected channel is switched off and the Over-Temperature Flag is set. Restart of the channel is done by deleting the Flag. This feature protects the device against uncontrolled temperature togglin
