Digital semiconductor single channel isolated gate driver chip (hereinafter referred to as digital isolated driver chip) is an integrated circuit used to drive power MOSFET or IGBT. The chip has the function of isolating power supply and signal, which can convert low-level logic signals into high-level driving signals, and achieve signal isolation, so that there is electrical isolation between input signals and output signals.
Digital isolation driver chip BC847BS It is mainly composed of input end, output end, isolation layer, drive circuit and power circuit. The input terminal receives the logic signal and isolates the signal through the isolation layer to ensure the electrical isolation between the input signal and the output signal. The driving circuit is responsible for converting the input signal into high-level driving signal, and driving the power MOSFET or IGBT through the output end. The power supply circuit provides the chip with the required working voltage.
