1% Accurate Battery Monitors Detect Up to Four Levels in Single- or Multicell Portable Devices
Maxim 1% Accurate Battery Monitors
SUNNYVALE, Ca. - Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX6782-MAX6790, low-power (5.7ľA), 1% accurate, battery monitors capable of monitoring up to four voltage levels. These devices are ideal for monitoring single lithium-ion (Li+) cells or multicell alkaline/NiCd/NiMH powered devices. Each of the four monitored levels offers an independent low-battery output indicator for early warning as the battery level decreases. Monitoring each battery level to within 1% accuracy lets the battery operate for a longer period between replacement or recharge.
The MAX6782-MAX6790 also feature adjustable thresholds with low-input bias currents. This allows use of large resistors to minimize current while maintaining threshold accuracy. These devices are offered with fixed or adjustable hysteresis to prevent the low-battery-output chattering often associated with battery-powered applications.
The MAX6782 / MAX6783 monitor four battery levels, the MAX6784 / MAX6785 three levels, and the MAX6786 / MAX6787/ MAX6788 two levels. The MAX6789 / MAX6790 feature quad-level overvoltage detectors with complementary outputs. The MAX6782 / MAX6784 / MAX6786 / MAX6789 are available with push-pull outputs, while the MAX6783 / MAX6785 / MAX6787 / MAX6790 are available with open-drain outputs. The MAX6788 is available with one open-drain and one push-pull output.
This family of devices is offered in space-saving 8-/10-pin TDFN and 3mm x 3mm, 12-/16-lead TQFN packages. They are fully specified from -40°C to +85°C. Prices start at $1.85 for the MAX6782 / MAX6783 / MAX6789 / MAX6790, $1.48 for the MAX6784 / MAX6785, and $1.13 for the MAX6786 / MAX6787 / MAX6788 (1000-up, FOB USA)
