How to calculate the current consumption of the device in stop mode at 25°C for DC Motor system IC TLE9560/1/2??

Parameter Parameter ID Typ. value at 25°C Comment
Base current in  in stop mode P_4.4.2 50 µA -
Current adder cyclic wake  P_4.4.26 18 µA Refer to note 12) for cyclic wake and 13) from TLE9562 datasheet
Additional current for one HS on
with 130 µs on / 50 ms off
(= 0.026 % duty cycle)
P_4.4.24 250 x 0.026% = 0.7 µA  250 µA is the additional current for the first HS in stop mode. This value must be multiplied by the duty cycle (ton / (ton + toff))
CAN wake capable P_4.4.17 4.5 µA -
LIN wake capable P_4.4.11 0.2 µA -
Total - 73 µA -

 

Notes 12) and 13) from TLE9562 datasheet

Note: 73 µA is the average current consumption of the device in the described conditions.

If additional functions are activated e.g. watchdog on, wake inputs are activated, overvoltage brake activated, the corresponding current adder must be taken into account.

The current consumption of the microcontroller must be also added.
