Abstract

A battery protection circuit (100) that prevents an over-discharge condition of a battery (16) and a reverse polarity battery charger protection circuit (200). The battery protection circuit (200) includes a battery input (70) configured to receive a battery voltage, a reference voltage input (19) configured to receive a low battery reference voltage, a comparator (U15) for comparing a first signal indicative of the battery voltage with a second signal indicative of the reference voltage and generating an output indicative of a low battery voltage, a feedback resistor (R172) coupling the output of the comparator (U15) to the reference voltage input to create hysteresis and a battery disconnect circuit (100) to disconnect the battery voltage applied to a load (34). The reverse polarity battery charger protection circuit (200) has relay and a diode to detect reverse polarity connection of the charge to the battery (16).
