Intelligent Sixfold Low-Side Switch

Siemens AG 

TLE 4216 G

Application Description

Applications in automotive electronics require intelligent power switches activated by

logic signals, which are shorted-load protected and provide error feedback.

The IC contains six power switches connected to ground (low-side switch). On inductive

loads the integrated Z-diodes clamp the discharging voltage.

By means of TTL signals on the control inputs (active high) all six switches can be

activated independently of another when a high level appears on the preferred-state

input. When there is a low level on the preferred-state input, switches 1 to 4 are switched

on, switches 5 and 6 are switched off regardless of the input level. The inputs are highly

resistive and therefore must not be left unconnected, but should always be on fixed

potential (noise immunity).

The status output signals the following malfunctions by analog voltage levels:

q Overload

q Overtemperature
