SNOSB14E August 2009 – July 2024 LPV521
PRODUCTION DATA
The rail-to-rail common-mode input range and the very low quiescent current make the LPV521 an excellent choice for use in high-side and low-side battery current-sensing applications. The high-side current-sensing circuit in Figure 7-7 is commonly used in a battery charger to monitor the charging current to prevent overcharging. A sense resistor RSENSE is connected in series with the battery.
