MIC5031中文资料麦瑞半导体数据手册PDF规格书

General Description

The MIC5031 MOSFET driver is designed to switch an N-channel enhancement-type MOSFET from a TTL control signal in a high-side switch application. The MIC5031 provides overcurrent protection, can accommodate loads with high-inrush current, and is designed to survive automotive power disturbances. This driver is suitable for up to 30kHz PWM operation with 0 to 100 duty cycle.
