Abstract
A battery monitor with programmable voltage references. The battery monitor includes a comparator circuit connected to a battery for receiving a voltage level thereof and to a voltage reference circuit for receiving a at least one reference voltage generated thereby. A trim circuit is connected to the voltage reference circuit for adjusting the reference voltage(s) and generated by the voltage reference circuit. The comparator circuit compares the voltage level of the battery with the reference voltage(s) generates an output based on the relative value of the battery voltage compared to the reference voltage(s). The trim circuit is programmable and includes a microprocessor connected to a programmable register and a memory. The microprocessor obtains trim data from the memory and writes the trim data to the programmable register.
