The P9028-0NBGI is a power management integrated circuit (PMIC) designed to provide power supply and voltage conditioning for portable devices in automotive and industrial applications. In the process, the P9028-0NBGI reduces system power consumption, cost and complexity. This PMIC already has been integrated with majority of products on the market today, such as tablets, set-top-boxes, navigation systems, infotainment systems and thousands of other mobile devices.

The P9028-0NBGI is designed for consistent performance at wide energy loads and temperatures and it is suitable for automotive applications such as Adaptive Light Control (ALC) in infotainment systems, CAN communication or tablet power supply. It integrates two step-down regulators, two inductor-based LDO regulators, a charge pump and a battery charger. This PMIC is especially suitable for automotive applications due to its very low dropout voltage, low external component count and low quiescent current.

The P9028-0NBGI’s working principle is based on a ripple current concept in which the total ripple current of the system is managed by highly efficient synchronous buck converters. This PMIC employs digital power technology, which allows it to dynamically adjust the supply voltage, current and temperature to achieve superior performance and improved power consumption. The voltage regulation feature also adapts the output voltage depending on the load and ensures that the system operates within the defined range. The P9028-0NBGI is designed for continuous low-power operation in order to maximize power efficiency and system reliability.

The P9028-0NBGI is also characterized with a wide variety of protection features. It can detect over voltage, overcurrent, under voltage, short-circuit and battery pre-charge conditions, and then either respond with a warning or shut down depending on the type of failure. In addition, the P9028-0NBGI also offers short-circuit protection, over-temperature protection, reverse voltage protection and active current limit protection.

The P9028-0NBGI is a highly efficient and reliable PMIC that offers superior performance and improved power consumption in automotive and industrial applications. It is designed for continuous low-power operation for maximum power efficiency, ideal for use in portable applications. The integrated features of this PMIC provide a high level of protection, making it a preferred choice for automotive suppliers and OEMs.
