Nisshinbo’s NP4271 LDO regulator incorporates a high-precision watchdog timer and reset features by window-type output voltage monitoring. Designed for automotive useful security, the collection meets the necessity for exterior MCU monitoring and dependable voltage-based reset features in digital management items (ECUs).
The LDO operates throughout a broad enter voltage vary of 4.0 V to 40 V and provides two output voltage choices of three.3 V or 5.0 V. Output voltage is correct to inside ±2.0% over a variety of situations, together with enter voltages from 6 V to 40 V, load currents from 5 mA to 500 mA, and temperatures starting from -40°C to +125°C.
Two reset perform choices can be found primarily based on output voltage monitoring. Model A displays each the high and low sides, whereas Model B displays solely the low facet. Detection voltage accuracy is ±2.0% for the low facet and ±5.0% for the excessive facet, throughout the total temperature vary. Moreover, the NP4271 gives excessive timing accuracy for each watchdog timer monitoring and reset occasions.
The NP4271 automotive LDO regulator is offered by Nisshinbo licensed distributors, together with DigiKey and Mouser.
