Maxim unveils 850-kHz/500-kHz SMBus-programmable battery chargers
February 08, 2011 // Paul Buckley
Maxim Integrated Products has introduced the MAX17435/MAX17535 SMBus battery chargers capable of operating at 850 kHz and 500 kHz, respectively. The SMBus interface enables programming of the charge settings without changing external components and maximizes design flexibility.
Programmable settings include charge current, charge voltage, input current limit, relearn voltage, and digital IINP voltage readback. Equivalent competitive solutions require the use of external components to program charge settings. The MAX17435/MAX17535 are ideal for notebook computers, ultra-mobile PCs (UMPCs), mobile internet devices (MIDs), and other battery-powered applications where space is critical.
The MAX17435/MAX17535 provide ±0.4% battery-voltage accuracy. Low-offset current-sense amplifiers deliver ±3% charge-current accuracy using 10 milohm sense resistors. An internal charge pump drives the adapter n-channel MOSFETs when the adapter is present, and a p-channel MOSFET selects the battery in the absence of an adapter.
Availability and Pricing
The MAX17435/MAX17535 are available in a space-saving, 4 mm x 4 mm, 24-pin TQFN package with an exposed backside pad. They are fully specified over the -40 to +85 degrees Celsius extended temperature range. Prices start at $6.43 (1000-up, FOB USA). An evaluation kit is available with recommended external components to reduce design time.
