Product details
Overview
ADP5090ACPZ-1-R7 from Analog Devices is an ultralow power boost regulator with integrated MPPT, charge management, and power path control for energy harvesting systems. It operates from 80 mV to 3.3 V input, delivers up to 800 mA at BAT, supports cold start from 380 mV, and features 320 nA quiescent current (CBP ≥ MINOP) - enabling self-powered wireless sensor nodes powered by PV cells or TEGs.
For engineers reviewing the ADP5090ACPZ-1-R7 datasheet, ADP5090ACPZ-1-R7 pinout, ADP5090ACPZ-1-R7 application, or ADP5090ACPZ-1-R7 equivalent, key selection criteria include cold-start capability, programmable MPPT ratio, battery overcharge/discharge thresholds, PGOOD flag behavior, and backup primary cell integration via BACK_UP pin.
Technical Context
The ADP5090ACPZ-1-R7 implements a hysteretic synchronous boost controller with integrated high-side and low-side MOSFETs (RHS_DS_ON = 1.38 Ω typ, RLS_DS_ON = 1.25 Ω typ), operating in pulse frequency mode (PFM) for sub-µW efficiency at ultralight loads. Its MPPT loop samples VIN open-circuit voltage every 19 s and holds it on CBP using a 10 nF capacitor to maintain operation at peak harvest power.
Energy storage management includes dual-threshold battery protection (VBAT_TERM = 2.2–5.2 V programmable, VBAT_SD = 2 V fixed), SYS-switch on-resistance of 0.48 Ω, and automatic power path arbitration between harvested energy, rechargeable storage (BAT), and optional primary cell (BACK_UP), with 185 mV comparator offset preventing backfeed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Cold-start input voltage | 380 mV typical - enables startup from weak photovoltaic or thermoelectric sources before system voltage builds |
| Input voltage range (post-cold-start) | 80 mV to 3.3 V - supports ultra-low-voltage energy harvesters including micro-PV and low-ΔT TEGs |
| Quiescent current (active) | 320 nA typical (CBP ≥ MINOP) - minimizes drain during intermittent light/heat conditions |
| MPPT sampling cycle | 19 s interval with 296 ms sampling window - balances tracking accuracy against system interruption time |
| Battery charge termination | Programmable 2.2 V to 5.2 V - matches Li-ion, thin-film, or supercapacitor voltage profiles |
| SYS switch on-resistance | 0.48 Ω typical - limits voltage drop under 800 mA load, preserving system rail stability |
| Backup path comparator offset | 185 mV typical - prevents BACK_UP pin from being charged by BAT or SYS, ensuring unidirectional flow |
Pinout & Package
The ADP5090ACPZ-1-R7 is housed in a 16-lead, 3 mm × 3 mm LFCSP package with exposed pad connected to AGND. Thermal resistance θJA = 53.1°C/W enables operation up to +125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SETSD | Battery discharge shutdown threshold input | Resistor divider sets fixed 2 V shutdown point - prevents deep discharge of Li-ion or thin-film batteries |
| TERM | Battery charge termination voltage input | Resistor divider programs 2.2–5.2 V cutoff - configurable for diverse storage chemistries |
| MINOP | Minimum operating power enable/disable | Resistor sets input voltage threshold; grounding disables MPPT and reduces IQ to 260 nA |
| MPPT | Maximum Power Point Tracking ratio setting | Resistor divider defines OCV scaling (e.g., 80% for PV, 50% for TEG) - determines optimal harvest point |
| CBP | MPPT reference hold capacitor node | 10 nF capacitor stores sampled OCV - maintains regulation reference between 19 s sampling intervals |
| DIS_SW | Boost regulator disable control | Logic-high signal halts switching within 1 µs - eliminates RF interference during transmission bursts |
| BACK_UP | Primary cell backup supply input | Enables automatic switchover when SYS drops below BAT; 400 mA capability with inrush limiting |
| PGOOD | System voltage status flag output | Open-drain logic-high when SYS > SETPG threshold - signals MCU that regulated rail is stable |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar energy harvesting power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC3331IDHD#PBF | Integrated buck-boost + AC/DC piezoelectric input; higher 680 nA IQ; no MPPT; 20 V max input | Better suited for piezoelectric or AC harvesters; lacks OCV-sampling MPPT for PV/TEG optimization | Select when harvesting from vibration or AC sources; avoid for PV/TEG where MPPT is essential |

FAQ
What is the minimum input voltage required for cold-start operation of the ADP5090ACPZ-1-R7?
The ADP5090ACPZ-1-R7 achieves cold-start operation from a minimum input voltage of 380 mV (typical) at the VIN pin when the SYS voltage is below 1.93 V. This capability is enabled by an internal charge-pump circuit and allows the ADP5090ACPZ-1-R7 to begin regulation even when no stored energy is present - critical for deploying truly battery-free systems powered solely by ambient light or heat.
How does the MPPT function work in the ADP5090ACPZ-1-R7, and what harvester types does it support?
The ADP5090ACPZ-1-R7 implements MPPT by periodically sampling the VIN open-circuit voltage (every 19 s for 296 ms), scaling it via a resistor divider at the MPPT pin, and holding the result on the CBP capacitor. This allows the boost regulator to operate at the input voltage corresponding to maximum power extraction. The ADP5090ACPZ-1-R7 supports both photovoltaic cells (MPPT ratio ≈ 80%) and thermoelectric generators (MPPT ratio ≈ 50%), with the ratio set externally - no firmware or calibration required.
Can the ADP5090ACPZ-1-R7 manage multiple energy storage elements simultaneously?
Yes, the ADP5090ACPZ-1-R7 manages three distinct power domains: harvested input (VIN), rechargeable storage (BAT), and optional primary-cell backup (BACK_UP). It autonomously arbitrates between them using internal comparators and power switches - for example, sourcing from BACK_UP when SYS falls below VSYS_TH and BAT is depleted. The ADP5090ACPZ-1-R7 does not require external logic to coordinate these paths, simplifying system architecture.
What is the purpose of the DIS_SW pin on the ADP5090ACPZ-1-R7, and how fast does it respond?
The DIS_SW pin on the ADP5090ACPZ-1-R7 provides hardware-level, RF-friendly control to temporarily halt boost switching - preventing electromagnetic interference during wireless transmission. Driving DIS_SW high disables the regulator within 1 µs (typical), and pulling it low resumes operation immediately. This feature is integral to the ADP5090ACPZ-1-R7's design for coexistence with 2.4 GHz BLE or sub-GHz LoRa radios in compact sensor nodes.
How is battery overcharge protection implemented in the ADP5090ACPZ-1-R7?
Battery overcharge protection in the ADP5090ACPZ-1-R7 is implemented via the TERM pin: an external resistor divider sets the VBAT_TERM threshold between 2.2 V and 5.2 V. When the BAT voltage exceeds this threshold, the ADP5090ACPZ-1-R7 disables the boost regulator. Hysteresis (3.7% typical) prevents oscillation, and regulation resumes only after BAT falls below VBAT_TERM_HYS. This fully hardware-based protection requires no MCU intervention and applies directly to the ADP5090ACPZ-1-R7's integrated charge control block.
