The traditional method of battery voltage detection is usually through a power supply voltage divider and sampling through the ADC to achieve detection. The voltage divider detection solution needs extra external circuits, which increases the system cost, volume and power consumption.
In portable electronics designs, typical battery-monitoring systems measure battery voltage and battery current to detect when the battery needs charging or replacement. In this post, I’ll demonstrate battery-voltage and current-monitoring circuitry for cost-optimized systems using operational amplifiers (op amps).
The circuit operates from a supply voltage as low as 1.7V and requires less than 2µA of supply current. This ensures that, even for a battery with a minimal remaining charge, the circuit still produces the correct output state. Table 2 provides typical component values to realize trip points for V BAT (V H->L and V L->H) battery monitoring.
Under-Voltage Detection with a 5-pin Comparator Typically the comparator and voltage reference are directly powered by the battery if their operating voltage range extends high enough to include the maximum battery voltage.
The battery sensor senses the external battery voltage value and compares it with the dc charging voltage of an Uninterrupted Power Supply. An alarm is designed to notify the personnel, in the event that the two voltages do not match in terms of value compares.
