The TPS3828-50DBVR is a supervisor IC that provides voltage monitoring of a single battery cell, as well as a reset output, in applications with multiple power domains. TPS3828-50DBVR reset output capability allows you to reset your processor or system in the event of an overvoltage or undervoltage condition. This supervisor IC is designed for use in either single cell Li-ion battery packs or other single cell applications, such as USB and wall power packs.

The TPS3828-50DBVR has a flexible reset output with programmable reset timeout and pins for adjusting the reset and reset timeout periods. A reset output provides for a reset of the system, processor, or other components in the event of an overvoltage or undervoltage condition. The TPS3828-50DBVR is qualified to the industrial temperature range of -40°C to +85°C and includes guard band protection against ESD on the battery and monitoring circuitry.

The TPS3828-50DBVR is ideal for battery applications such as those used in portable electronics. It is also suitable for automotive battery management systems, as well as other single cell applications such as wall power packs or USB power packs.

TPS3828-50DBVR application field

The TPS3828-50DBVR is designed for use in applications with multiple power domains. These include portable electronic applications with a single cell Li-ion battery pack; automotive battery management systems; and wall/USB power packs.

The TPS3828-50DBVR has been designed to monitor one battery cell and communicate with other power domain ICs. It meets all requirements of a cell monitoring circuit and provides synchronous, low-voltage reset outputs.

The reset output of the TPS3828-50DBVR has been designed to be compatible with popular microcontrollers, microprocessors, and ASICs. Its reset output can be used to reset the system in the event of an overvoltage or undervoltage condition.

TPS3828-50DBVR working principle

The TPS3828-50DBVR voltage supervisor provides voltage monitoring of a single cell, as well as various reset management functions. It has two pins for setting the reset and reset timeout periods, and two pulses for setting the reset hysteresis and reset timeout thresholds. The voltage supervisor contains a threshold detection circuit that monitors the cell voltage and a reset generator that generates a reset signal.

The reset generator includes a comparator that is permanently connected to the cell voltage and the voltage supervisor’s threshold detection circuit. When the cell voltage falls outside of the programmed threshold levels, the comparator kicks in and the reset generator generates a reset signal. The reset signal can be used to reset the system, processor or other components in the event of an overvoltage or undervoltage condition.

The TPS3828-50DBVR is protected against ESD on the monitoring and battery circuitry from the outside world, resulting in improved robustness and reliability. The device is available in an 8-pin chip-scale package (UQFN) for increased precision and improved efficiency.
