What are the key features of MIC2019A-1YM6TR?
- Fixed and adjustable current limiting protects downstream loads from overcurrent faults without external sense resistors
- 5 V supply operation in a 6-pin thin TSOP package for compact power distribution rail implementations
- Tape-and-reel (TR) packaging enables automated SMT assembly in high-volume power management designs
What is MIC2019A-1YM6TR used for?
The MIC2019A-1YM6TR is suited for USB power distribution, motherboard peripheral supply protection, and hot-plug power sequencing in embedded systems operating from a 5 V rail. Its current-limiting function prevents overcurrent damage to USB ports, SD card slots, and peripheral connectors in industrial HMI panels, single-board computers, and set-top boxes. The compact 6-pin TSOP package fits tight PCB areas near connectors where a full-size power switch IC would not fit.

Frequently Asked Questions
What supply voltage does the MIC2019A-1YM6TR support and how is its current limit configured?
The MIC2019A-1YM6TR operates from a 5 V supply and offers both fixed and adjustable current limit settings. The adjustable configuration allows designers to set the overcurrent threshold using an external resistor, enabling precise protection levels for different load types such as USB peripherals, SD card interfaces, or sensor modules on a shared 5 V bus.
How does the MIC2019A-1YM6TR protect a USB port in a 5 V powered hub design?
The MIC2019A-1YM6TR limits inrush and fault currents on the 5 V USB power output, preventing damage to the host power supply and PCB traces when a short-circuit or excessive-load device is connected. The current-limiting switch transitions to a controlled limiting mode instead of instantly disconnecting, reducing voltage transients and allowing the connected device to boot within its 500 mA or 900 mA USB power budget.
What PCB space does the MIC2019A-1YM6TR occupy and why is the thin TSOP package beneficial near connectors?
The MIC2019A-1YM6TR comes in a 6-pin thin TSOP (TSOP6) package with a footprint of approximately 2.9 mm x 1.6 mm and 0.9 mm profile height. The thin profile is ideal for placement directly adjacent to USB or card connectors on constrained boards, avoiding height conflicts with connector housings and shields in compact embedded platforms and industrial I/O modules.
When should a designer use MIC2019A-1YM6TR instead of a simple resettable fuse on a 5 V peripheral supply?
The MIC2019A-1YM6TR is preferred over a resettable polyfuse when fast, repeatable current limiting with an active enable signal is required. Unlike a polyfuse that takes seconds to reset after a fault, the MIC2019A-1YM6TR recovers within microseconds after the overcurrent condition clears, and its enable input allows the host MCU to explicitly switch the 5 V supply on or off for controlled power sequencing or remote reset of a misbehaving peripheral.
