TLE8110ED

Smart Multichannel Low Side Switch with Parallel Control and SPI Interface

Power Outputs

7.1

Description Power Outputs

The TLE8110ED is a 10 channel low-side powertrain switch. The power stages are built by N-channel power

MOSFET transistors. The device is a universal multichannel switch but mostly suited for the use in Engine

Management Systems [EMS]. Within an EMS, the best fit of the channels to the typical loads is:

• Channel 1 to 4 for Injector valves or mid-sized solenoids with a nominal current requirement of 1.5A,

• Channel 5 to 6 for mid-sized solenoids or Injector valves with nominal current requirement of 1.7A,

• Channel 7 to 10 for small solenoids or relays with a nominal current requirement of 0.75A.

Channel 1 to 10 provide enhanced clamping capabilities of typically 55V best suited for inductive loads such

as injectors and valves. It is recommended in case of an inductive load, to connect an external free wheeling-

or clamping diode, where-ever possible to reduce power dissipation.

All channels can be connected in parallel. Channels 1 to 4, 5 to 6 and 7 to 10 are prepared by matching for

parallel connection with the possibility to use a high portion of the capability of each single channel also in

parallel mode (refer to Chapter 7.4).

Channel 5 and 6 have a higher current shut down threshold to allow to connect in parallel mode a load with

high inrush-current, such as a lambda sensor heater.
