Key Features
- Ultra-low quiescent current enables extended battery life in IoT and wearable sensor nodes
- Wide input voltage range of 0.82 V to 5.25 V supports single-cell Li-ion and alkaline battery sources
- Automatic input-to-output bypass mode eliminates efficiency loss when input exceeds output voltage
- Programmable low-battery detection threshold with power-good (PGT) flag for safe system shutdown
Applications
The MCP16411-I/UN is ideal for single-cell Li-ion, alkaline, or NiMH battery-powered IoT sensors, wireless nodes, and wearable devices requiring efficient step-up conversion from 0.82 V to regulated 3.3 V or 5 V outputs. Its ultra-low quiescent current in PFM mode maximizes runtime in always-on applications such as asset trackers and environmental loggers. The automatic bypass mode and low-battery indicator simplify power management firmware in microcontroller-based portable devices.

Frequently Asked Questions
What input voltage range does the MCP16411-I/UN support for battery-powered designs?
The MCP16411-I/UN operates from a minimum input of 0.82 V to a maximum of 5.25 V, covering single-cell alkaline batteries down to their end-of-life voltage, as well as fully charged single-cell Li-ion at 4.2 V, enabling boost conversion across the entire usable battery discharge curve.
How does the automatic bypass mode in the MCP16411-I/UN improve system efficiency?
When the input voltage rises above the programmed output voltage, the MCP16411-I/UN automatically switches to a direct input-to-output bypass path, eliminating switching losses and reducing power dissipation below 1 mW at light loads, which is critical for maximizing battery runtime in wearable and IoT sensor applications.
What package is the MCP16411-I/UN available in and how does it fit compact PCB layouts?
The MCP16411-I/UN is available in a 10-pin MSOP package with a typical body size of 3 mm × 3 mm, providing a compact footprint suitable for space-constrained wearable boards and coin-cell-powered IoT modules where standard 8-pin SOIC packages would occupy significantly more PCB area.
How does the programmable low-battery detection help protect devices using the MCP16411-I/UN?
The MCP16411-I/UN's low-battery comparator monitors input voltage against a resistor-divider-set threshold and asserts the PGT (power-good) flag when voltage drops below the programmed level, giving the host microcontroller advance warning to save state data before the supply rail collapses below 0.82 V minimum input.
