Abstract: Battery monitors are provided in association with battery stacks to monitor the health of individual batteries. This is important as damaged batteries present a fire risk. Usually the battery stack is assembled and connected to a multipin connector assembled and connected to a multipin connector which engages with a cooperating connector of a battery monitor. The connections have a tolerance so the connections make in a random and uncontrolled order. This disclosure provides ways of ensuring that the power supply connector connects first. This reduces voltage stress in the monitoring circuit and also allows steps to be taken to control inrush currents.

Abstract: An analog multiplexer may be used for sampling an input voltage that is capable of having a higher voltage level than an upper supply voltage. The analog multiplexer includes a plurality of input switch circuits and a shorting switch circuit. The plurality of input switch circuits include n-type or p-type laterally diffused field effect transistors (NLDFETs or PLDFETs). At least one of the input switch circuits includes a level shifting switch circuit that is able to sample an input voltage that is greater than the upper supply voltage for the multiplexer. A shorting switch circuit, at an output of the multiplexer, includes a capacitively coupled gate drive circuit and is configured to short a first differential output to a second differential output after the input voltage is sampled.
