MAX6656MEE+

MAX6656MEE+ is a precise voltage and temperature monitor. The digital thermometer reports the temperature of two remote sensors and its own die temperature. The remote sensors are diode-connected transistors typically a low-cost, easily mounted 2N3906 PNP type that replace conventional thermistors or thermocouples. Remote accuracy is ±1°C for multiple transistor manufacturers with no calibration necessary. The remote channels can also measure the die temperature of other ICs, such as microprocessors, that contain a substrate-connected PNP with its collector grounded and its base and emitter available for temperature sensing purposes. The temperature is digitized with an 11-bit resolution. It also measures its own supply voltage and three external voltages with 8-bit resolution. It is used in applications such as notebooks, thin clients, servers, workstations, communication equipment, and desktop PC.

• Programmable under/over-threshold alarms

• Standby current is 3µA typical at (SMBus static, STBY = GND)
• Monitoring cycle time is 625ms typical at (VCC = +3.0V to +3.6V)
• Serial clock frequency is 400KHz maximum at (VCC = +3.0V to +3.6V)
• Operating temperature range from -55°C to +125°C
• 16-pin QSOP package
