TLE9260-3QX
Application Information
Note: Unused outputs are recommended to be left unconnected on the application board. If unused output pins
are routed to an external connector which leaves the ECU, then these pins should have provision for a zero
ohm jumper (depopulated if unused) or ESD protection.

Purpose / Comment
Capacitances
C1
68µF
Buffering capacitor to cut off battery spikes, depending on application
C2
100nF
EMC, blocking capacitor
C3
22µF
Buffering capacitor to cut off battery spikes from VSHS as separate supply
input; Depending on application, only needed if VSHS is not connected to
VS;
C4
2.2µF low ESR
As required by application, min. 470nF for stability
C5
100nF ceramic
Spike filtering, improve stability of supply for microcontroller;
not needed for SBC
C6
2.2µF low ESR
Blocking capacitor, min. 470nF for stability;
if used for CAN supply place a 100nF ceramic capacitor in addition very
close to VCAN pin for optimum EMC behavior
C7
33nF
As required by application, mandatory protection for off-board connections
C8
33nF
As required by application, mandatory protection for off-board connections
C17 47pF
Only required in case of off-board connection to optimize EMC behavior,
place close to pin
C18 47pF
Only required in case of off-board connection to optimize EMC behavior,
place close to pin
C9
10nF
Spike filtering, as required by application, mandatory protection for off-board
connections (see also Simplified Application Diagram with the Alternate
Measurement Function)
C10 10nF
Spike filtering, as required by application, mandatory protection for off-board
connections
C11 10nF
Spike filtering, as required by application, mandatory protection for off-board
connections
C12 4.7nF / OEM dependent Split termination stability
