• Manufacturer Part Number: TLE4216G
• Description: Intelligent Sixfold Low-Side Switch
• Manufacturer: Siemens Semiconductor Group

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:
