- 30a current sensing with current sense amplifier (csa)
refsense003-evk-001 is a reference design with a current sense amplifier: bd14210g-la and a shunt resistor: ltr50uzpfu, which can be considered for current measurement using a shunt resistor. current measurement circuits are used in various devices for high-side/low-side current sense, overcurrent sense, and current control of motors. the reference designs of shunt resistors and current-sense amplifiers presented on this website can be used for various current measurements as a solution that offers both high accuracy and small area. design data and reference boards are available for purchase. please make use of them to reduce your design man-hours.
- built-in 1ch current sense amplifier bd14210g-la/shunt resistor ltr50.
- achieves current sense accuracy of 1%
- supports current sense up to 30a
- connectable with ad converter bu79100g-la-evk-001
