rsdio writes: SMBus is similar to I2C, and should therefore be easily connected to most PIC or AVR projects.
Highly integrated, 850kHz/500kHz SMBus-programmable battery chargers:
MAX17435/MAX17535, highly integrated SMBus™ battery chargers capable of operating at 850kHz and 500kHz, respectively. Unlike competitive solutions, MAX17435/MAX17436 allow the charge setting to be programmed via the SMBus interface, eliminating the need for external components and improving design flexibility. Programmable settings include charge current, charge voltage, input current limit, relearn voltage, and digital IINP voltage readback. 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.
Test: is wordbooker working again?
this post is up on FB but the last one before this is about the breakout boards.
