MIC2077-2BM中文资料麦瑞半导体数据手册PDF规格书

General Description

The MIC2027 and MIC2077 are quad high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection. The MIC2027/77 are internally current limited and have thermal shutdown that protects the device and load.

特性 Features

• 150mΩ maximum on-resistance per channel

• 2.7V to 5.5V operating range

• 500mA minimum continuous current per channel

• Short-circuit protection with thermal shutdown

• Thermally isolated channels

• Fault status flag with 3ms filter eliminates false assertions

• Undervoltage lockout

• Reverse current flow blocking (no “body diode”)

• Circuit breaker mode (MIC2077) reduces power consumption

• Logic-compatible inputs

• Soft-start circuit

• Low quiescent current

• Pin compatible with MIC2524 and MIC2527

Applications

• USB peripherals

• General purpose power switching

• ACPI power distribution

• Notebook PCs

• PDAs

• PC card hot swap
