SP2526A-1EN-L is a kind of power distribution switches and load drivers pf power management integrated circuit (PMIC) developed by Shanghai SUPERchip Semiconductor Co., Ltd. It can realize switch function and load parameter adjustment of the whole system power distribution network in the electronic system, so as to solve the problem of system power distribution and allocation. With its excellent performance, SP2526A-1EN-L can be widely used in electronic products such as digital display, notebook computer, game machine, multimedia display, server, high-end tablet, power communication equipment and other digital products, and can fully meet the personalized switching voltage and current demands of many digital equipments.SP2526A-1EN-L consists of one high-side MOS switch and four low-side MOS switches, which can be managed independently. The MAX high-side on-resistance of the MOS switch is 1.5Ω, and the MAX high-side energy is about -7.5mJ. The four low-side MOSFETs have the same parameters, and the on-resistance is 0.5Ω.The working principle of SP2526A-1EN-L\'s MOS switch is based on the control of the gate voltage. When the gate voltage is higher than the threshold voltage of the MOS, the inversion layer at the bottom of the gate insulates the source and the drain, and the electrical connection between the two is cut off. Otherwise, a low gate voltage makes the inversion layer disappear, and the source and the drain become electric connection, so the power distribution network achieves the purpose of switching.In addition, each low-side MOSFET also has an internal current sense amplifier, which can achieve an accuracy current limit of digital control of 5mV, and the accuracy range of load current setting is 0.1A to 20A. The built-in soft-start circuit can limit the inrush current generated during start-up, and can delay the time of the load current limit, which can reduce the peak inrush current during the turn-on of the system.In short, SP2526A-1EN-L is a very reliable power distribution switch and load driver PMIC, which has the advantages of low conduction and switch loss, fast switch response, easy application of external power supply, and accurate setting of load current, which can meet the needs of different electronic products.
