Battery monitors keep watch on four
levels
Low-power battery monitor ICs are ideal for monitoring single lithium-ion cells or multicell alkaline/NiCd/NiMH powered devices.
The MAX6782-MAX6790 are low-power (5.7uA), 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

Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
Low-power serial ADC runs up to 200Ksample/s
New from Maxim Integrated Products, the MAX1162 serial-interface 16bit A/D convertor connects directly to SPI, QSPI and Microwire devices without additional interface logic.
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 minimise 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 and MAX6783 monitor four battery levels, the MAX6784 and MAX6785 three levels, and the MAX6786, MAX6787 and MAX6788 two levels.
The MAX6789 and MAX6790 feature quad-level overvoltage detectors with complementary outputs.
The MAX6782, MAX6784, MAX6786 and MAX6789 are available with push-pull outputs, and the MAX6783, MAX6785, MAX6787 and 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 3 x 3mm, 12-/16-lead TQFN packages.
They are fully specified from -40 to +85C.
Prices start at US $1.85 for the MAX6782, MAX6783, MAX6789 and MAX6790, $1.48 for the MAX6784 and MAX6785, and $1.13 for the MAX6786, MAX6787 and MAX6788 (1000-up, FOB USA).
