        正極OVP芯片,耐壓36V,限流1A, 采用SOT23-6/DFN2*2-8封裝形式,適用于掛脖耳機以及其他穿戴式產品,常用于搭配4054和4056等充電芯片使用,當然亦可單獨使用,因為很多主控都帶有充電功能,可完全pin LP5300等 
        The HP2604 is a front-end over voltage and over
        current protection device. It achieves wide input
        voltage range from 2.8VDC to 36VDC. The over voltage
        threshold is set to internal default setting. The low
        resistance of integrated power path nFET switch
        ensures better performance for battery charging
        system applications. It can deliver up to 1A current to
        satisfy the battery supply system. It integrates the
        over-temperature protection shutdown and auto
        recovery circuit with hysteresis. Also, it integrates
        over current protection function and recovery
        Absolute maximum input voltage: 36V
        Maximum load current: 1A
        Low power path resistance:
