EMC1702-1-KP-TR General Description

The EMC1702-1-KP-TR is a versatile product that combines high-side current sensing with precision temperature measurement. By measuring the voltage across an external sense resistor, it accurately represents the high-side current of a battery or voltage regulator. Additionally, it monitors the bus voltage to calculate power consumption effectively. The device is equipped with bidirectional peak detection circuitry, allowing it to detect sudden current spikes and flag them based on programmable thresholds
