Designed to enhance the reliability and functional safety of automotive electronic control units (ECUs) and industrial equipment, the NP4271 series is a versatile power management solution that operates within a wide voltage range of 4.0 to 40 V, making it suitable for use in demanding environments.
With an output voltage accuracy of ±2.0% over a broad temperature range from -40°C to 125°C it ensures stable performance under extreme conditions. The product is available with an output voltage of 3.3V or 5.0V, catering to different system requirements.
One of the key features of the NP4271 is its robust watchdog timer (WDT) function, which contributes to overall system safety by monitoring the output pulses of a microcontroller unit (MCU) and providing a reset whenever these pulses remain absent for a certain period, indicating that the software experienced some lock-up issue.
Additionally, it has an integrated window voltage detector, ensuring that any positive and negative deviations in the power supply to the MCU are promptly detected, allowing for immediate corrective actions. This single-chip solution simplifies the design of power supply systems by integrating various monitoring functions that would otherwise require multiple components.
Next to its monitoring features, it is designed with improved transient response characteristics and is said to outperform comparable products even with smaller output capacitors. This makes the NP4271 particularly effective in applications where power lines experience frequent fluctuations due to the switching operation of other components. The product's ability to maintain stable output with minimal voltage deviations underscores its suitability for automotive and industrial applications where reliability is critical.
The NP4271 series is AEC-Q100 Grade 1 and is available in a compact HSOP-8-AC package, providing an efficient and space-saving solution for design engineers.
