The LTC2946CDE#PBF is a rail-to-rail System Monitor measures current, voltage, power, charge and energy. It features an operating range of 2.7 to 100V and includes a shunt regulator for supplies above 100V. The current measurement common mode range of 0 to 100V is independent of the input supply. A 12-bit ADC measures load current, input voltage and an auxiliary external voltage. Load current and internally calculated power is integrated over an external clock or crystal or internal oscillator time base for charge and energy. An accurate time base allows the LTC2946 to provide measurement accuracy of better than ±0.6% for charge and ±1% for power and energy. Minimum and maximum values are stored and an over-range alert with programmable thresholds minimizes the need for software polling. Data is reported via a standard I²C interface. The LTC2946 I²C interface includes separate data input and output pins for use with standard or opto-isolated I²C connections.

• Additional ADC input monitors an external voltage
• Continuous scan and snapshot modes
• Stores minimum and maximum values
• Alerts when limits exceeded
• Split SDA pin eases opto-isolation
• Internal ±5% or external time bases
• Shutdown mode with IQ <40µA
• Delta-sigma ADC with less than ±0.4% total unadjusted error
• >100V Shunt regulator for supplies
• 12-bit Resolution for current and voltages
• ±1% Accurate power and energy measurements
• ±0.6% Accurate current and charge measurements
