The RT9742JNGV is a member of Richtek\'s family of electric power management integrated circuits (PMICs). It is a high bandgap voltage driven IC, dedicated to enhanced system power distribution, high-side and low-side load driving and load shunting. The RT9742JNGV is applied to control electric switching in loads such as motors, solenoids, and LED modules. It is designed with low quiescent current, low switching losses and robustness in order to increase system efficiency, save power and extend battery life. The RT9742JNGV also features an advanced bootstrap architecture that allows it to operate at higher input voltages.The RT9742JNGV has a dedicated B-Factor (current sense amplifier) with an input current range from 1mA to 40mA and an adjustable voltage reference from 0.6V to 5.2V. This output is via an integrated error amplifier, which increases accuracy for small current sensing applications. Thermal sensing is also integrated into the RT9742JNGV, so it can compensate for thermal drift.The RT9742JNGV also has integrated fault protection to ensure the safety and reliability of the system. It includes overload, under voltage, over voltage, reverse voltage and short circuit detection. These protections protect the system from over current and short circuit conditions.The RT9742JNGV also includes a power control manager with shutdown and inform output pins. This allows the system to control other circuits and inform the system of any detected faults.The RT9742JNGV is a versatile power management integrated circuit (PMIC) ideal for high side and low side load driving, load shunting and enhanced system power distribution. Its low quiescent current and low switching losses make it an efficient choice for power management applications, while its thermal sense and fault protection features ensure reliable performance. Additionally, with its advance bootstrap architecture, the RT9742JNGV can operate at higher input voltages. Overall, it is a versatile solution for many power management applications.
