... Comparator) Control Signal Threshold 2 (15-mV Comparator) U6432B 4 The U6432B is protected against damage in case of battery reversal via resistor R ground (-31). An integrated protection circuit together with external resistances R R limits the current pulses in the IC. 4 The arrangement of the supply connections to Pin 2 (and 6) must ensure that on the connection printed circuit board (PCB), the resistance of V than that to Pin 2 ...
