I. Device Description
The MAX1788 is completing final qualification.
A. General
The MAX1788 smart battery-pack controller integrates a user programmable microcontroller core, a
Coulomb-counting fuel gauge, a multi-channel data-acquisition unit, protection drivers, and SMBus™
v1.1 compliant master/slave SMBus interface. The 8-bit RISC microcontroller core integrates 8k bytes
of user programmable flash and an 8k byte ROM library. This provides battery-pack designers with
complete flexibility in developing fuel gauging and control algorithms. The MAX1788 is equipped with
ISD (In System Debug) capability for efficient firmware development and debugging.
The MAX1788 includes a 12-bit data-acquisition unit to measure individual cell voltages, thermistors,
instantaneous current and pack voltage. Individual cell voltage measurements with 0.5% accuracy and
overcurrent protection to provide first level protection. Internally adjustable over-current thresholds and
delay timers provide a flexible solution.
The integrating fuel gauge module has a typical input offset of 1µV, and gain accuracy of better than
1% with no trimming required during pack manufacture. The MAX1788 has a wide 4V to 25V operating
voltage range, and is available in a 28 pin TSSOP. The MAX1788 EvKit, development tools and
reference design are available..
