In April, 2009 the European Commission adopted the implementing measure for external power supply products. The regulation comes into force on April 27th, 2009 and the cut-off date for the first stage’s requirement is 27th April 2010.

The Eco-design Directive for Energy-related Products establishes a framework under which manufacturers and importers of Energy-related products (ErP) will, at the design stage, be obliged to increase energy efficiency and reduce products’ negative environmental impacts. The ErP Directive itself does not include any requirements for specific products. It is the implementing measures (IMs) that provide the prescription for compliance for each product category.

The IM for external power supplies is referred to as the Commission Regulation 278/2009. After cut-off date (27th April 2010) for the first stage requirement, any product falling into the scope sold on the EU market has to meet the ErP directive by complying with this IM.

Several characteristics make the MAX8900 perfect for high-reliability systems. The MAX8900 is protected against input voltages as high as +22V and as low as -22V. Battery protection features include low voltage prequalification, charge fault timer, die temperature monitoring, and battery temperature monitoring. The battery temperature monitoring adjusts the charge current and termination voltage as described in the JEITA specification for safe use of secondary lithium-ion batteries.

Charge parameters are easily changeable with outside components. An external electrical resistance sets the charge current from 50mA to 1200mA. Another external resistor adjusts the prequalification and done current thresholds from 10mA to 200mA. The done current threshold is very accurate achieving ±1mA at the 10mA level. The charge timer is adjustable with an external capacitor.

The MAX8900 dc-dc battery charger is available in a 0.4mm pitch 2.44mm x 2.67mm x 0.64mm WLP package.
