describe
EG2131 is a cost-effective high-power MOS transistor, IGBT transistor gate drive dedicated chip, which integrates logic signal input processing circuit. circuit, dead-time control circuit, under-voltage shutdown circuit, blocking circuit, level shift circuit, pulse filter circuit and output drive circuit, dedicated to Drive circuits in brushless motor controllers.
The high-end working voltage of EG2131 can reach 300V, the low-end Vcc power supply voltage range is 11V~20V, and the static power consumption is less than 100uA. The core The chip has a blocking function to prevent the output power tubes from being turned on at the same time. The input channel HIN has a built-in 200K pull-down resistor, and LIN has a built-in pull-up 5V. High potential, when the input is floating, the upper and lower power MOS transistors are turned off, the output current capability is IO+/- 1/1.5A, and the SOP8 package is used.
