Micrel MIC2074
The MIC2074 offers “smart” shutdown that reduces current consumption in fault mode. When a fault occurs due to thermal shutdown, the output is latched off. The MIC2074s’ output will be reset, enabling the output, either by removing the load or toggling the ENABLE pin.| Part No. | MIC2074 |

GENERAL DESCRIPTION
FEATURES
The MIC2073/2074 are high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection. The MIC2073/2074 are internally current limited and have thermal shutdown for protecting the device and load. Both devices employ soft-start circuitry that minimizes inrush current in applications where highly capacitive loads are employed. A fault status output flag is asserted during overcurrent or thermal shutdown conditions. Transient faults are internally filtered. The MIC2073/2074 are available in an 8-pin SOIC.● 115 mΩ typical RBDS(ON) at 5.0 V
● 210 mΩ maximum RBDS(ON) at 5.0 V
● 2.7 V to 5.5 V operating range
● 500 mA minimum continuous current per channel
● Short circuit protection with thermal shutdown
● Thermally isolated channels
● Fault status flag (FLGA/B) separate for each channel
● 3ms fault flag delay (TD) eliminates false assertions
● UVLO (Undervoltage Lockout)
● Reverse current flow blocking (no “body diode”)
