New Tiny, Programmable USB/AC Switch-mode Battery Chargers with Integrated CurrentPath™ Manager from Summit Electronics
Summit Microelectronics has introduced two more members of its third-generation programmable battery charger integrated circuit (IC) family.
The SMB136 and SMB137B employ CurrentPath technology, providing dual input source (USB or AC/DC) with arbitration, dual output for system and battery and system operation with a dead or missing battery. Both products support all battery charging standards: USB 2.0 Specification, USB On-The-Go Supplement, USB Battery Charging Specification 1.0, IEEE1725 Standard, Chinese USB Charging Specification, and others.
Furthermore, the SMB136 and SMB137B are the only battery charger ICs with CurrentPath to detect the input source type (USB host/hub, AC/DC, etc.) and automatically optimize operation for the fastest and safest battery charging. Both products meet the European Union Memorandum of Understanding, issued on June 29th, 2009, for standardized mobile phone charger.
Both products operate with an input range from +3.5V to +6.2V input and safely withstand continuous input over-voltage up to +18V (non-operating), while protecting downstream circuitry. Both the SMB136 and the SMB137B are offered in a tiny 3.0mm x 2.5mm, 30-ball, lead-free chip-scale (CSP) with an operating temperature range of –30C to +85C.
