MIC2026
MIC2026 is Dual-Channel Power Distribution Switch manufactured by Micrel Semiconductor.
Description
Features
The MIC2026 and MIC2076 are high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection.
The MIC2026/76 are internally current limited and have thermal shutdown that protects the device and load.
The MIC2076 offers “smart” thermal shutdown that reduces current consumption in fault modes. When a thermal shutdown fault occurs, the output is latched off until the faulty load is removed. Removing the load or
- 140mΩ maximum on-resistance per channel
- 2.7V to 5.5V operating range
- 500m A minimum continuous current per channel
- Shortcircuit protection with thermal shutdown
- Thermally isolated channels
- Fault status flag with 3ms filter eliminates false assertions
- Undervoltage lockout toggling the enable input will reset the device output.
- Reverse current flow blocking (no “body diode”)
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 and thermal shutdown conditions. Transient faults are internally filtered.
- Circuit breaker mode (MIC2076)
