Nisshinbo Micro Devices NJW4250
High-precision voltage tracker
The NJW4250 voltage tracker operates up to an absolute maximum voltage of 45 V and provides an output current of 50 mA. The adjustable input reference voltage ranges from 2.5 V to 36 V and is replicated to the tracking output voltage with a guaranteed accuracy of ±5 mV over the entire operating temperature range. The NJW4250 has protection circuits such as thermal shutdown and over-current protection, which are ideal for off-board sensors in automotive applications and ensures high reliability. The low quiescent current of 40 μA and small SOT-23-5 package make the NJW4250 an energy-efficient and space-saving solution.
