The LM4132DQ1MFT3.0 device is a precision high-side current rail monitoring IC with low quiescent current from Texas Instruments’ Power Management (PMIC) Voltage Reference family of products. It is intended to monitor a High Side bus current up to 8A and may also be used as a general purpose current sense monitoring device. The device includes an integrated drive transistor, protection circuitry, and voltage feedback capability. It is available in a 3mm x 4mm, 8-terminal QFN package with a 0.5mm pitch. The LM4132DQ1MFT3.0 is a versatile device that is well suited for battery-powered and always-on portable applications such as smartphones, tablets and notebooks. With the integrated features of the device, it can provide over-current protection and monitoring as well as precision current sensing on the high side. The device also features a shutdown pin to enable and disable the device without additional external transistors or protection circuits.The LM4132DQ1MFT3.0 features two input pins: one for the current source and one for the high side current rail. The current source pin is used to read the voltage drop across an external sense resistor to enable precision current sensing. The high side current rail pin is used to compare the current rail voltage to an internally set reference voltage, which prevents the device from operating at over-voltage conditions. The voltage feedback pin allows the device to more accurately sense and monitor the current rail as it varies. The device is also capable of resetting itself after a fault event and will continue working at the set threshold.The device includes an integrated high-side n-channel drive transistor, which is capable of driving a wide range of loads with low quiescent current, making it an ideal solution for battery-operated applications. The integrated protection circuit includes an over-current, under-voltage lockout (UVLO) and a thermal overload protection. The device also includes an output driver which is capable of driving an external P-channel or N-channel MOSFET for applications requiring higher current outputs. The LM4132DQ1MFT3.0 provides a reliable solution for current monitoring and load switching applications. It is designed to handle current up to 8A and is ideal for applications involving high-side current sensing and monitoring in portable systems including smartphones, tablets, and notebooks. With its integrated features, it provides over-current protection and extends battery life in battery-powered devices. Its low quiescent current drive transistor makes it a great choice for always-on applications. Its voltage feedback function provides better accuracy and reliability in monitoring applications.
