MAX6776

      Here are some general descriptions of the MAX6776. The MAX6776 low-power, 1%-accurate battery monitors are available in the ultra-small DFN package (1.0mm x 1.5mm) and SC70 packages. These low-power devices are ideal for monitoring single lithium-ion (Li+) cells, or multicell alkaline/NiCd/NiMH power sources. These devices offer single low-battery outputs and feature fixed or resistor-adjustable hysteresis. Hysteresis eliminates the output chatter sometimes associated with battery voltage monitors, usually due to input-voltage noise or battery terminal voltage recovery after load removal. These devices are available in several versions: with single- or dual-voltage monitors, and with fixed or adjustable hysteresis. The MAX6776 offer a
single battery monitor and factory-set hysteresis of 0.5%, 5%, or 10%. For convenient interface with system power circuitry or microprocessors, both open-drain and push-pull outputs are available. The single-channel devices are available with open-drain or push-pull outputs. The dual-channel devices MAX6776 are available with both outputs open-drain, both outputs push-pull, or one of each. This family of devices is offered in small 5-pin SC70 and ultra-small 6-pin DFN packages, and is fully specified over the -40°C to +85°C extended temperature range.
      Here are some characteristics of the MAX6776. The MAX6776 has 1.0%-accurate threshold specified over temperature, single/dual, low-battery output options low 3a battery current ,open-drain or push-pull low-battery outputs, fixed or adjustable hysteresis, low-input leakage current allows use of large resistors, guaranteed valid low-battery-output logic state down to vbatt is 1v, immune to short battery transients, fully specified from -40°c to +85°c and small 5-pin sc70 or ultra-small 6-pin dfn (1mm x 1.5mm) package.
      Here are some absolute maximum ratings of the MAX6776. BATT to GND is -0.3V to +6V. LBI, LBL, LBH, LBI1, LBI2 to GND is -0.3V to minimum of when VBATT is + 0.3V and +6V. LBO, LBO1, LBO2 to GND (open-drain) is -0.3V to +6V. LBO, LBO1, LBO2 to GND (push-pull) is -0.3V to minimum of when VBATT is + 0.3V and +6V. Input Current (all pins) is 20mA. Output Current (all pins) is 20mA. Continuous Power Dissipation when TA = +70°C. 5-Pin SC70 when derate is 3.1mW/°C above +70°C) is 247mW. 6-Pin DFN when derate is 2.1mW°C above +70°C) is 168mW. Junction Temperature is +150°C. Storage Temperature Range is -65°C to +150°C. Lead Temperature when the soldering  10s is +300°C.
