This battery manager is ideal for a variety of different applications, including but not limited to portable electronics, wearables, automotive, industrial, and medical.

PMIC - Battery Chargers

A power management integrated circuit (PMIC) battery charger is an integrated circuit designed to optimize and control the charging of a rechargeable battery, typically by a DC power source. Battery chargers are used in a variety of applications such as laptop, medical, and portable electronics.The DS2712ZB+ PMIC battery charger is a versatile and efficient battery manager tailored to meet a wide range of applications. It features two low impedance MOSFETs that manage the charging and discharging of the battery while optimizing full charging and full discharging. The device has a user programmable charge voltage that is adjustable through existing programming solutions. It has several features that help to extend the battery life and cycle life, including linear charge control, timeout charge control, charge termination, and control of low battery voltage.The device also provides several safety features, such as short and over-temperature protection, overcharge protection, charge overcurrent protection, battery overvoltage protection, and reverse current protection. These safety measures help to prevent damage to the battery from overcharging and reduce the risk of fire and other hazards.

Working Principle

The working principle of the DS2712ZB+ PMIC battery charger is simple. The incoming voltage from the external power source is buffered and regulated by the linear regulator. This regulator provides the regulated charge voltage to the battery, while the input voltage is monitored and the charge current is adjusted based on the external power level. The device also supports programmable charge current limits, which helps to protect the battery from overcharging.Once the charge current has been adjusted to the desired level, the linear regulator drives the charge voltage to the battery in a linear fashion. As the voltage of the battery rises, the regulator reduces the charge current until the battery is fully charged. The charge current is then cut off, and the termination threshold is reached, which terminates the charging process.The DS2712ZB+ PMIC battery charger also supports timeout charging, which turns off the charging process after a predefined time period. This helps to prevent the battery from reaching its maximum voltage and overflow state. Additionally, the device also supports trickle charging, which helps to maintain the battery when in the stand-by mode.Additionally, the DS2712ZB+ PMIC battery charger also supports a user programmable low battery voltage, which helps to detect when the battery voltage has dropped below a programmable threshold. This helps to prevent the battery from over-discharging and avoids excessive current draw from the battery. This feature helps to extend the battery life and cycle life. In summary, the DS2712ZB+ PMIC battery charger is a versatile and effective battery manager tailored to meet a wide range of applications. It features two low impedance MOSFETs that efficiently manage the charging and discharging of the battery, while optimizing trickle and full charging. The device also features several features, including linear charge control, timeout charge control, charge termination, and control of low battery voltage, which help to extend the battery life and cycle life, as well as provide safety measures to ensure the safety of the battery.
