Description
EG2131 300V 1.5A half bridge IGBT and MOSFET Gate Driver IC SMD SOP8
Chip description
EG2131 is a cost-effective high-power MOS tube and IGBT tube gate drive chip. It integrates a logic signal input processing circuit, a dead-time control circuit, an under voltage shutdown circuit, a latch circuit, a level shift circuit, and a pulse circuit. Filter circuit and output drive circuit, dedicated to the drive circuit in brushless motor controllers. The high-end operating voltage of EG2131 can reach 300V, the low-end Vcc power supply voltage range is wide from 11V to 20V, and the static power consumption is less than 100uA. The chip has a latch 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. LIN It has a built-in pull-up 5V high potential, which keeps the upper and lower power MOS tubes in a closed state when the input is left floating. The output current capacity is IO+/-1/1.5A, and it is packaged in SOP8.
