Описание (английский):

IEC 62637-1:2011 defines a charging interface between small handheld multimedia devices and power-supply accessories, specifically chargers. Devices, which could be based on this standard may vary over time, but have to comply with the limited power available. The interface is a 2 mm barrel type charging interface. The French version of this standard has not been voted upon. This bilingual version (2011-07) replaces the English version.

Overview - IEC 62637-1:2011 (2 mm barrel interface)

IEC 62637-1:2011 specifies a standardized battery charging interface between small handheld multimedia devices and power‑supply accessories (chargers). The physical interface is a 2 mm barrel connector and the standard defines the electrical and mechanical interfaces, charger identification, and accessory connection rules. It does not cover full charger internals or device internal functions; chargers and devices must still meet applicable EMC and safety standards.

Key topics and technical requirements

The standard focuses on practical electrical limits and connector details to ensure interoperability and device protection:

Connector type: 2 mm barrel charging plug/receptacle with defined mechanical details.

Charger output capacitance: maximum 1000 µF (+20%) for output voltages below 7 V; linearly reduced to 700 µF (+20%) at 9.3 V.

Transient limits:

Maximum charger output overshoot: 16 V.
Maximum reverse voltage at charger output: 1 V.
Maximum settling time after load change: 10 ms (to within ±10%).
Maximum duration of charging current overshoot (>1.1 A): 5 ms.
Maximum output voltage undershoot for load currents ≤100 mA: 4.1 V.

Ripple and noise:

Maximum output ripple 300 mV RMS for output voltages between 2.5 V and 5.5 V.
Total peak‑to‑peak ripple across 0 Hz–1 MHz limited to 800 mV p‑p.

Charging window & current behavior: defined charging voltage/current window and requirements for current linearity and control (see clause 5.6).

Accessory interfaces: electrical specifications for accessories placed between charger and device, plus rules for device booting when connected to accessories.

Charger identification: defined method for identifying charger capabilities via the interface.

Applications and who uses this standard

IEC 62637-1 is intended for organizations designing and manufacturing:

Mobile phones, MP3 players, digital cameras, portable GPS and gaming devices.

Charger and power‑supply accessory manufacturers.

OEMs and contract manufacturers who need a consistent 2 mm barrel charging interface to ensure cross‑compatibility and safe charging behavior.

Test labs and compliance engineers evaluating charger‑to‑device interoperability and transient/noise performance.

Practical benefits include simplified accessory ecosystems, reduced risk of damage from wrong chargers, and predictable performance across devices using limited power budgets.

Related standards

Devices and chargers must still comply with applicable national/international EMC and safety standards referenced in product dossiers.

Keywords: IEC 62637-1, 2 mm barrel interface, battery charging interface, charger specifications, output capacitance, ripple voltage, charger identification, small handheld multimedia devices.
