BSC624-12V-B

7.1.11 Pin 21 AI1, pin 22 AI2, pin 23 AI3

INFORMATION

Via these three analogue inputs, two different functions each can be realised optionally:



1 mA – current supply for external 5

kΩ potentiometer



kΩ pull-up resistor for external 33 kΩ NTC temperature sensor.

Internal wiring



Each of the three analogue inputs can be individually programmed. When setting all three inputs as current

supply, it is possible to implement the following functions for instance:



pin 21

AI1

: LV voltage control



pin 22

AI2

: Buck mode current limit



pin 23

AI3

: Boost mode current limit



During the set-up for the temperature measurement (T

min

= 25°C) of external components, for instance, the

following configuration is possible:



pin 21

AI1

: Battery temperature



pin 22

AI2

: Cooling water temperature



pin 23

AI3

: Reserve

Pin 21 AI1
Pin 22 AI2
Pin 23 AI3
