Q67000-A9094

Manufacturer Part Number
Q67000-A9094
Description
Intelligent Double Low-Side Switch 2 x 0.5 A
Manufacturer
SIEMENS [Siemens Semiconductor Group]
Datasheet
Type
TLE 4214 G
Intelligent Double Low-Side Switch 2 x 0.5 A
Features
Application
Applications in automotive electronics require intelligent power switches activated by
logic signals, which are shorted-load protected and provide error feedback.
This IC contains two of these power switches (low-side switches). In case of inductive
loads the integrated clamp diodes clamp the discharging voltage. If a “high” signal is
applied to the enable input both switches can be activated independently of one another
with TTL signals at the control inputs (active high). The high impedance inputs should
always be connected to a fixed potential (noise immunity).
The status output (open collector) signals the following malfunctions with high potential:
