MIC2026/2026A/2076/2076A
Dual-Channel Power Distribution Switch
General Description
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 shut-
down fault occurs, the output is latched off until the faulty load
is removed. Removing the load or toggling the enable input
will reset the device output.
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.
The MIC2026/76 are available in 8-pin DIP or 8-lead SOP.
Features
• 140mΩ maximum on-resistance per channel
• 2.7V to 5.5V operating range
• 500mA minimum continuous current per channel
• Shortcircuit protection with thermal shutdown
• Thermally isolated channels
• Fault status flag with 3ms filter eliminates false asser-
tions (MIC2026A/2076A with 10ms filter)
• Undervoltwww.sony.com/clieage lockout
• Reverse current flow blocking (no “body diode”)
• Circuit breaker mode (MIC2076)
• Logic-compatible inputs
• Soft-start circuit
• Low quiescent current
• Pin compatible with MIC2526
Applications
• USB peripherals
• General purpose power switching
• ACPI power distribution
• Notebook PCs
• PDAs
• PC card hot swap
