SGM48535A/B数据手册SGMICRO中文资料规格书

描述 Description

The SGM48534A, SGM48534B, SGM48535A, and SGM48535B are single-channel low-side power transistor gate drivers. Inputs are compatible with standard CMOS or LSTTL signals. The output is capable of delivering 2.6A sink and 4.2A source peak currents. The SGM4853XA/B have over-current protection functions. The OCP pin detects the over-current signal, and the EN/nFLT pin outputs the over-current status. Once the over-current protection is triggered, the fault pin is pulled down internally and outputs a low level. The EN/nFLT pin requires an external pull-up circuit to ensure the normal operation of the driver. The EN/nFLT pin can also be used as an enable pin for the driver. Pulling the EN/nFLT pin low can disable the driver. The driver has under-voltage protection function, and the output remains low when the VCC voltage is lower than the operating voltage.

The SGM4853XA/B are all available in a Green SOT-23-6 package.
