Overview
The MIC2547-1BTS is a dual high-side power switch from Microchip Technology, designed for low-loss DC power distribution. It operates within a supply voltage range of 2.7V to 5.5V and supports an output current up to 500mA per channel. The device features adjustable current limiting between 100mA and 1.5A, with a maximum on-state resistance of 120mΩ. It includes reverse current blocking capabilities and typical on-state supply current of 100µA per channel.
Feature Summary
- Dual high-side switching architecture optimized for low-loss DC power distribution applications
- Adjustable current-limit functionality allowing precise control over load protection thresholds
- Reverse current flow blocking mechanism eliminates body diode conduction for enhanced isolation
Applications
- Advanced Configuration and Power Interface (ACPI) power management systems
- Low-loss DC power switching circuits requiring dual independent channels
- Power distribution units needing programmable current limit protection
Procurement Notes
Verify the specific suffix 'BTS' indicates the 16-pin TSSOP package configuration when sourcing. Confirm that the component is manufactured by Microchip Technology, as Micrel was previously associated with this series. Ensure the datasheet matches the exact part number for accurate electrical specifications regarding current limits and operating temperatures.
Selection Notes
Select this component when dual-channel high-side switching with adjustable current protection is required. The 120mΩ maximum on-resistance makes it suitable for efficient power distribution. Consider the 2.7V to 5.5V input range compatibility with your system logic levels. The TSSOP package offers a compact solution for space-constrained designs.
Part Context
The MIC2547 series integrates dual high-side switches optimized for ACPI and general power management. The MIC2547-1BTS specifically denotes the dual-channel variant in a 16-pin TSSOP package. This family addresses the need for reliable power distribution with built-in protection mechanisms against overcurrent conditions in embedded systems.
Replacement Considerations
MIC2547-1YM is a pin-compatible alternative in a different package. MIC2547-2BTS-TR offers similar functionality with potential packaging variations. Verify electrical parameters match before substitution.
