Description
Communication
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 ¹⁾.
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.
Reset
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.
