The TLE84110EL has two power supply inputs: The half bridge outputs are connected to
connected to the 12V automotive supply rail. The internal logic part is supplied by a separate voltage

voltage drop outs or disturbances on
without having to resend commands to the device.
A rising edge on
internally is deleted, and the outputs are switched to high-impedance status (tristate). A 10µF electrolytic and
100nF ceramic capacitor are recommended to be placed as close as possible to the
for improved EMC performance in the high and low frequency band.
5.2.2
The TLE84110EL enters low power mode (or sleep mode) by setting the INH input to low. The INH input has an
internal pull-down resistor. In sleep-mode, all output transistors are turned off and the SPI register banks are reset.
5.2.3
The TLE84110EL requires an external reverse polarity protection. During reverse polarity, the freewheeling diodes
across the half bridge output will begin to conduct, causing an undesired current flow (
to battery and excessive power dissipation across the diodes. As such, a reverse polarity protection diode is
recommended (see
