Description Power Outputs
The TLE8110EE 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 a 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 a high
inrush-current, such as a lambda sensor heater.
