ADCMP380

Data Sheet Ultralow Power Voltage Comparator with Reference ADCMP380 FEATURES Comparator with on-chip reference Ultralow power consumption with ICC = 92 nA (typical) Precision low voltage monitoring down to 0.5 V Accurate internal reference level over full temperature range ±1.6% at 1 V ±2.2% at 0.5 V Enable input 23 μs typical propagation delay Open-drain type output Input glitch immunity Available in a 1.46 mm × 0.96 mm WLCSP Operational temperature range: −40°C to +85°C APPLICATIONS Portable/battery-operated equipment Battery monitors Energy harvesting GENERAL DESCRIPTION The ADCMP380 is an ultralow power voltage comparator with internal reference suitable for use in general-purpose applications. The ultralow power consumption of this device makes it suitable for power efficiency sensitive systems, such as battery-powered portable devices and energy meters. The ADCMP380 is available with a 0.5 V and 1 V internal reference with ±2.2% and ±1.6% accuracy, respectively, over the full temperature range; this internal reference enables the device to monitor the node of interest accurately to 0.5 V. The enable input allows the user to hold the output low regardless of the state of the input. FUNCTIONAL BLOCK DIAGRAM VCC ADCMP380 EN IN OUT REF 12783-001 GND Figure 1.
