BQ24032ARHLT PMIC - Battery Chargers

The BQ24032ARHLT is a Power Management Integrated Circuit (PMIC), specifically a battery charger. It is designed to power many different electronic devices and is used extensively in many industries, including the automotive, medical, and telecommunications fields. It supports a range of battery types, including Nickel-Cadmium (NiCd), Lithium-Ion (Li-ion), and Lead-Acid (SLA) batteries. This PMIC is cost-effective and easy to use.The BQ24032ARHLT is an open-drain linear charger with a typical 5V minimum input voltage, and support for an adjustable output current from 0A to 3A. It comes with a 10-bit digital-to-analog converter (DAC) that can be programmed to adjust the charging voltage for each cell, allowing for customization for different battery types. It has an onboard voltage-drop detector that keeps the output voltage within tolerance, and the input current at a safe level. A thermistor can be connected to monitor the temperature of the battery and the system, allowing the charging process to be shut down if the temperature is too high.The BQ24032ARHLT is also equipped with an advanced power-management system, allowing the device to monitor the status of the system and the battery, and adjust the charging current accordingly. The power-management system can also be programmed to detect low-input voltage and high-temperature conditions, and switch to a low-power mode if these conditions occur. It can also detect when the battery is full and stop charging.The BQ24032ARHLT also supports a range of safety features, including over-voltage protection, over-temperature protection, and over-current protection. These features ensure that the battery does not overheat or become damaged, resulting in a longer lifespan for the battery and the device.The BQ24032ARHLT is a highly efficient and reliable PMIC that is suitable for a wide range of applications. It is easy to use and can be programmed to suit the needs of numerous applications. Its advanced power-management system allows it to monitor the system and the battery, and protect them from overloads and temperature fluctuations. In addition to its safety features, the device can be programmed to decrease the charging current when the battery is full and ensure a longer battery lifespan. The BQ24032ARHLT is an effective and cost-efficient solution for charging battery supplies in a variety of applications.
