Product details
Overview
EFP0110GM20-ER from Silicon Labs is a wired-boost configuration Energy Friendly Power Management IC (PMIC) designed for ultra-low-power battery-powered systems, delivering a fixed 3.327 V VOA output, OFF-state VOB (0.8–1.26 V programmable), and 1.870 V VOC output from 1.8–3.6 V input. It integrates Coulomb counting, I²C control, IRQ signaling, and EM4 support with 300 nA quiescent current (EM2, single output enabled), targeting EFM32/EFR32-based IoT sensors and wearables.
For engineers reviewing the EFP0110GM20-ER datasheet, EFP0110GM20-ER pinout, EFP0110GM20-ER application, or EFP0110GM20-ER equivalent, key selection criteria include its wired-boost topology, VOB startup-OFF behavior, QFN20 3×3 mm package, -40 to +100 °C junction temperature range, and compatibility with primary Li/FeS₂ or dual-alkaline batteries in metering and home automation devices.
Technical Context
The EFP0110GM20-ER implements a firmware-configurable wired-boost DC-DC A converter (VOA = 3.327 V at startup) paired with a dedicated buck-only DC-DC B (VOB, OFF at startup) and linear regulator VOC (1.870 V). Its architecture supports lossless Coulomb counting, I²C direct-mode energy mode transitions, and EM4 retention with coarse regulators.
It operates across 1.8–3.6 V input, uses BB_CTRL3.BB_MODE = 7 for wired-boost operation, disables VOB at power-on via VOB_EM0_V/VOB_EM2_V register defaults, and relies on external inductors for both DC-DC stages while integrating LDO C functionality only in select variants-not active in EFP0110GM20-ER's configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 3.6 V - supports dual alkaline, Li/FeS₂, or NiMH primary cells without external regulation. |
| VOA Output Voltage | 3.327 V (fixed at startup) - provides stable rail for RF SoCs like EFR32BG22 in low-power wireless applications. |
| VOB Startup State | OFF - eliminates standby leakage in secondary supply paths until firmware enables it (0.8–1.26 V programmable range). |
| Quiescent Current (EM2) | 300 nA (single output enabled) - enables multi-year battery life in EM2 sleep mode for sensor endpoints. |
| Coulomb Counter | Lossless, no sense resistor - measures charge delivered to load with ±1% accuracy per datasheet Section 3.4.1. |

Package: QFN20 (3 mm × 3 mm, 0.5 mm pitch), wettable flank, exposed thermal pad (GND-connected). Compliant with JEDEC MO-220, RoHS and REACH.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDA | Analog Supply Input | Supplies internal ADC, temp sensor, and voltage monitors; requires local 100 nF decoupling. |
| VDDB | Main Power Input | Primary battery input (1.8–3.6 V); feeds DC-DC A/B and coarse regulators. |

Applications
| Smart Utility Metering | Wireless Sensor Node |
|---|---|
|
Use Scenario: Battery-powered gas/water meter with LoRaWAN or NB-IoT uplink, operating 10+ years on two AA alkaline cells. IC Role / Device Role / Timing Role: Primary PMIC supplying EFR32MG24 MCU core (VOA), radio PA bias (VOB), and ADC reference (VOC) with Coulomb counting for battery health analytics. Use Value: Wired-boost topology maintains 3.3 V output down to 1.8 V input; EM2 quiescent current ≤300 nA extends battery life beyond 12 years. |
Use Scenario: Sub-GHz environmental sensor node deployed outdoors, logging temperature/humidity every 5 minutes and transmitting hourly.

|
Use Scenario: Passive infrared motion detector with BLE beacon, powered by single CR123A lithium primary cell. IC Role / Device Role / Timing Role: Supplies EFM32PG12B MCU (VOA), IR sensor bias (VOB), and precision reference (VOC); manages wake-from-EM4 on PIR interrupt. Use Value: -40 to +100 °C operation ensures reliability in garage/attic environments; UVLO hold at 1.2 V prevents brownout resets during cold starts. |
Use Scenario: Disposable ECG patch monitoring heart rate continuously for 7 days using coin-cell battery. IC Role / Device Role / Timing Role: Powers AD8232 analog front-end (VOC), microcontroller (VOA), and Bluetooth LE radio (VOB); Coulomb counter tracks battery depletion for end-of-life alert.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| EFP0109GM20-E | Identical wired-boost configuration but VOB enabled at startup (1.858 V), not OFF. | Suitable where secondary rail must be active immediately post-reset (e.g., always-on sensor bias). | Select EFP0109GM20-E only if VOB startup enable is required; otherwise EFP0110GM20-ER reduces leakage. |
| TPS63802DRLR | Buck-boost converter only (no integrated Coulomb counter, no I²C, no EM4 coarse regulators). | Used in cost-sensitive consumer electronics where battery telemetry and deep-sleep retention are not needed. | Choose TPS63802DRLR for simpler, lower-BOM-cost boost-buck needs-but lacks EFP0110GM20-ER's energy-mode intelligence and metrology. |
Compared with EFP0109GM20-E, EFP0110GM20-ER reduces system standby current by disabling VOB at boot; versus TPS63802DRLR, it adds firmware-configurable energy modes, lossless battery gauging, and EM4 retention-critical for certified medical and utility-grade deployments.

FAQ
What is the default VOB output state at power-on for EFP0110GM20-ER?
The EFP0110GM20-ER initializes VOB in OFF state at power-on, as confirmed in Table 3.1 OPN-Specific Features. This behavior minimizes leakage in secondary power domains until firmware explicitly enables VOB via I²C register writes to VOB_EM0_V/VOB_EM2_V. The programmable range remains 0.8–1.26 V once enabled.
Does EFP0110GM20-ER support Coulomb counting with the VOA boost output active?
Yes, EFP0110GM20-ER supports lossless Coulomb counting on the VOA rail regardless of DC-DC A operating mode. The counter measures charge delivered to the load without a sense resistor, and its accuracy is maintained during wired-boost operation per Section 3.4.1 of the datasheet-enabling precise battery depletion tracking in EFP0110GM20-ER-based systems.
What package type and dimensions does EFP0110GM20-ER use?
EFP0110GM20-ER uses a QFN20 package measuring 3 mm × 3 mm with 0.5 mm pin pitch and an exposed thermal pad. Per Section 9.1 of the datasheet, it complies with JEDEC MO-220, features wettable flanks for solder inspection, and requires standard reflow profiles for lead-free assembly.
Can EFP0110GM20-ER operate from a single Li/MnO₂ primary cell?
No-EFP0110GM20-ER's specified input range is 1.8 V to 3.6 V, while a single Li/MnO₂ cell operates from 1.8 V to 3.2 V. Though the lower bound matches, the upper limit (3.2 V) falls below EFP0110GM20-ER's 3.6 V max. For Li/MnO₂, EFP0101GM20-E (1.8–5.5 V) or EFP0106GM20-E (1.8–5.5 V, Buck/Boost) are validated alternatives.
How is the 3.327 V VOA output set in EFP0110GM20-ER?
The 3.327 V VOA output is factory-programmed and fixed at startup for EFP0110GM20-ER, derived from the VOA_V register value (VOA_V = 53) using the equation VOA(V) = 1.7374 V + (VOA_V × 0.0306 V). This value is immutable in hardware and does not require runtime I²C configuration-ensuring deterministic power-up behavior in EFP0110GM20-ER designs.
