The MC34VR500V4ESR2 is a high accuracy signal voltage supervisory IC specially designed for battery applications with low power consumption. It is a low standby current, low quiescent current, microprocessor-controlled battery protection IC which combines a low power voltage supervisor and internal Li-ion battery monitoring element.

Its application field is mainly in mobile communication, consumer electronics and other applications requiring low current and low power consumption. The main uses are as follows:

  • To optimize the power performance of digital electronic products for battery powered applications, especially for mobile operations.
  • For the protection of Li-ion batteries in digital handheld products, such as laptop and digital cameras.
  • For Li-ion battery monitoring, e.g. monitoring the battery status, providing over-charge and over-discharge protection, and reporting battery capacity.

The MC34VR500V4ESR2 is a microprocessor controlled device which includes a low power voltage supervisor, an internal Li-ion battery monitoring element and a low power voltage reference to monitor battery voltage and charge/discharge current.

The device integrates three main power management functions: battery capacity reporting, over-charge/discharge protection and power-on reset (POR) capability. It is usually used to monitor battery voltage and charge/discharge current, and to provide over-charge/discharge protection. Its working principle is simple and reliable. When battery voltage drops below a certain threshold, it generates a voltage supervisory output to instruct the microprocessor to shut down the system in order to prevent the system from further damage due to over-discharge, then it will generate a reset output to the microprocessor to reset the system before the voltage rises again, thus preventing the system from further damage.

The MC34VR500V4ESR2 is also highly integrated, so that the system designers can save bill of materials cost and PCB space as well. Furthermore, it includes several low power consumption techniques, such as voltage comparison, which offers very precise protection and accurate setting to the IC.

The MC34VR500V4ESR2 is an attractive power management solution, which offers good performance while maintaining a low quiescent current, low standby current and precise operation. The integrated low power consumption and precise setting make it an ideal choice for mobile and consumer applications where battery safety is highly desired.
