DS28E22P+T

The DS28E22P+T is an 8-pin device which solves power-delivery problems in battery-powered applications. This device is particularly useful when operating environment contains intense heat, moisture, humidity, and other potentially destructive factors which can damage the battery and its related components. This device is specifically designed for two particular applications; battery-powered systems and automotive power-delivery systems.

In battery-powered systems, the DS28E22P+T manages and monitors the energy stored in the battery pack and maximizes the usable capacity of the battery. It contains two primary stages, each of which manages energy in different applications. The first stage, mA Sense, regulates the current of the battery pack and helps to extend its life by controlling the charging or discharging capacity. The second stage, mV Sense ensures accurate voltage measurements, along with providing a simple way to detect when the battery is drained and close-down the system. The DS28E22P+T also contains logic block which controls the external circuit, and enable/disable signals.

In automotive applications, the DS28E22P+T is used to control and monitor the power-delivery system. This includes providing a regulated output voltage, controlling the charging regime, and measuring the sensed power. The first key component is the power-supply control, which regulates the output voltage of the system. This ensures that the isolated output power is consistent and stable. Second, the DS28E22P+T also controls the charging regime by monitoring the charge and discharge currents. Finally, the mV Sense module is used to detect the minimum and maximum voltages of each battery cell.

The DS28E22P+T also provides additional features including events, timers, and a built-in temperature sensor. The events component provides a logging solution by recording specified conditions, such as optocoupler events, voltage events, and charging events. Additionally, the DS28E22P+T contains two real-time-clock timers which can be used to control an event or a system component. Moreover, the built-in thermistor sensor enables the system to take into account the temperature of the battery, and if necessary shut down the system depending on the ambient temperature in order to prevent it from damage.

The DS28E22P+T is a versatile memory component which solves two key application-field; battery-powered systems and automotive power-delivery systems. It contains two primary stages, mA Sense and mV Sense, along with events, timers and a built-in temperature sensor. These features enable the component to accurately control and monitor the current, voltage, and temperature of any given system.
