Key Features
- Ultra-low supply voltage range of 1.8V to 3.6V enables direct use in modern low-power battery applications
- 200mA continuous current rating with integrated reverse current protection in a tiny 4-pin MLF package
- Built-in overvoltage protection and thermal shutdown for robust system reliability
Applications
The MIC94300YMT TR is well suited for portable consumer electronics, wearables, and IoT devices where a controlled 200mA power rail must be switched on and off under a 3.6V supply. Its compact 4-pin MLF footprint and low quiescent current make it ideal for battery-powered designs requiring efficient load management. It also finds use in USB accessories and handheld instruments that need integrated reverse-current blocking to protect sensitive downstream components.

Frequently Asked Questions
What supply voltage range does the MIC94300YMT TR support, and how does that affect battery-powered design?
The MIC94300YMT TR operates from 1.8V to 3.6V, making it directly compatible with single-cell Li-ion and LiPo batteries discharged to 2.7V. This 1.8V lower limit allows the switch to remain operational even as a coin cell or lithium battery nears end-of-life, extending usable product runtime without additional voltage regulation stages.
How much load current can the MIC94300YMT TR switch, and is that enough for a BLE sensor module?
The device is rated for 200mA continuous load current, which comfortably covers most Bluetooth Low Energy sensor modules that typically peak below 15mA during radio bursts. The 200mA headroom also accommodates small microcontrollers, sensors, and their decoupling capacitors, allowing the MIC94300YMT TR to power an entire sensor node from a single switch.
What protection features are integrated in the MIC94300YMT TR to reduce BOM count?
The MIC94300YMT TR integrates overvoltage protection, reverse current blocking, and thermal shutdown in a single 4-pin MLF package. These built-in safeguards eliminate the need for external protection diodes and TVS clamps, reducing BOM cost and saving board space in designs with tight 4mm x 4mm or smaller layout budgets.
When would MIC94300YMT TR be preferred over a discrete MOSFET switch at 3.3V?
The MIC94300YMT TR is preferable when design time and PCB area are constrained, because its 4-pin MLF package integrates gate drive, reverse protection, and fault handling that would otherwise require 5 to 8 discrete components. At a 3.3V rail with loads up to 200mA, the integrated solution also offers more predictable on-resistance and faster enable response than a manually biased MOSFET.
