NPM1100-QDAB-R

Battery Management Overview

The nPM1100-QDAB-R is a compact Power Management IC (PMIC) from Nordic Semiconductor, integrating a linear battery charger and a dual-mode configurable buck regulator. It supports Li-ion and Li-Po batteries with charge currents ranging from 20 to 400 mA. The device features a USB-compatible system regulator with input voltages of 4.1–6.7 V and 20 V overvoltage protection. The buck regulator delivers up to 150 mA at pin-selectable output voltages of 1.8 V, 2.1 V, 2.7 V, or 3.0 V, achieving conversion efficiency up to 92%. An unregulated system rail provides up to 660 mA between 3–5.5 V. Ship mode current is 460 nA.

Battery Management Feature Summary

• Fully pin-configurable architecture eliminates the need for software-based configuration or control logic.
• Dual-mode buck regulator automatically switches between hysteretic and PWM modes for optimized efficiency.
• Integrated dynamic power path manages simultaneous charging and system load distribution.
• Includes NTC thermal protection and JEITA compliance for safe battery management.

Battery Management Applications

• Wearable electronic devices
• Personal medical equipment
• IoT sensors
• Remote controls

Battery Management Procurement Notes

Verify that the suffix -QDAB-R corresponds to the specific termination voltage variant required for the design. Confirm package type and reel specifications match procurement requirements. Ensure compatibility with target operating temperature range of -40°C to 85°C. Check for any specific handling instructions related to the QFN or WLCSP package if applicable.

Battery Management Selection Notes

Select this component when space constraints are critical, as the total solution footprint can be as low as 23 mm². Choose the nPM1100-QDAB-R specifically if the application requires the termination voltage associated with this suffix. Consider its high efficiency for extending battery life in portable devices where discrete components would exceed available PCB area.

Battery Management Part Context

The nPM1100 series represents Nordic Semiconductor's entry into dedicated power management solutions, designed to complement their wireless SoCs like the nRF52 and nRF54 series. It consolidates functions previously requiring multiple discrete chips into a single ultra-compact package, simplifying BOM and layout for IoT and wearable applications.

Battery Management Replacement Considerations

Public documentation does not list direct cross-references or mandatory substitutes for the nPM1100-QDAB-R. Designers should evaluate the nPM1300 for enhanced feature sets or other nPM series variants if pin-compatibility or specific electrical parameters differ significantly.
