The SM5021ADH-EL is a single-channel high-side MOSFET driver, manufactured by NPC, designed to drive N-channel enhancement-mode MOSFETs in applications requiring high-side switching. It incorporates a charge pump to generate the necessary gate voltage for the MOSFET, simplifying the external circuitry. The driver also features under-voltage lockout (UVLO) protection, which prevents damage to the MOSFET by ensuring it is not driven when the supply voltage is too low. Its fast turn-on and turn-off characteristics contribute to efficient switching performance.

Applications:

• High-side switching applications in automotive electronics.
• Industrial control systems requiring high-side load control.
• Battery management systems for charge and discharge control.
• Power distribution networks in various electronic devices.
• LED lighting systems for controlling the power to LED arrays.

Features:

• Single-channel high-side MOSFET driver.
• Integrated charge pump for gate voltage generation.
• Under-voltage lockout (UVLO) protection.
• Fast turn-on and turn-off times.
• Low quiescent current consumption.
• Wide operating voltage range.
• Surface mount package for easy integration.

Benefits:

• Simplified design due to the integrated charge pump, reducing the need for external components.
• Enhanced MOSFET protection from undervoltage conditions, increasing reliability.
• Improved system efficiency due to fast switching speeds and minimized power losses.
• Stable operation across a wide range of supply voltages.
• Compact footprint for space-constrained applications.
