Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•LTC4150 measures battery consumption and charging in handheld PC and portable product applications. The device monitors the current flowing through an external detection resistor located between the positive electrode of the battery and the battery load or charger to obtain the voltage at both ends of the detection resistor, and then integrates the signal in multiple stages to infer the amount of electricity.
•Output in the form of a pulse at the interrupt pin of the device, the frequency of the pulse is the detection voltage, and the number of pulse periods is the Coulomb number. These pulses correspond to a fixed amount of charge flowing into or out of the battery, and use polarity to indicate whether the battery is discharging or charging.
•The accumulated battery charge and discharge quantity can be measured Operating temperature: -40°C to 85°C volt-to-frequency gain:32.55 When the power supply is below 2.5V, undervoltage lock output Induced voltage Differential input (SENSE+-SENSE-) range: -50mV to 50mV.
•V10: Default power supply 5V, after short connecting SJ2 and SJ3, use 3.3V power supply SJ1 pad is disconnected by default. Short-circuit automatic clearing interrupt +0UT:SENSE+ load supply end, battery charging input end, inductive current positive input end +IN:SENSE- inductive current negative input end and positive end of battery power supply under test SHDN: digital shutdown input, low effective.
•POL: Indicates the battery current polarity output. When the current flows into the battery in high voltage times, the value is low The current is discharged from the battery CLR: Clears interrupt numeric input INT: Charge count interrupts drain open output
