Key Featrues

Wide Input Voltage Range (2V to 36V): The MAX20039/MAX20040 ICs support a broad input voltage range, enabling operation in challenging conditions such as cold-crank scenarios in automotive applications. This ensures reliable performance even during voltage fluctuations, making it ideal for automotive and industrial environments.
High Output Current (0.6A/1.2A): With a maximum output current of 0.6A (MAX20039) or 1.2A (MAX20040), these ICs can power a wide range of loads efficiently. This capability is particularly useful for applications like infotainment systems and point-of-load (POL) power supplies, where higher current demands are common.
Low Quiescent Current (52µA): The ICs feature an ultra-low quiescent current of 52µA in standby mode, helping designers meet stringent OEM current requirements. This enhances energy efficiency, especially in battery-powered or start-stop systems, by minimizing power consumption during idle states.
High Switching Frequency (200kHz to 2.2MHz): The adjustable switching frequency allows for the use of smaller external components, reducing the overall footprint and cost of the design. This feature also improves efficiency and enables compact designs for space-constrained applications like body electronics and power over coax (POC).
Integrated H-Bridge Architecture: The ICs incorporate an integrated H-bridge architecture, which simplifies design and reduces the need for external components. This integration enhances efficiency, lowers BOM costs, and saves board space, making it suitable for compact and cost-sensitive applications.
Spread Spectrum for EMI Reduction: The ICs offer spread spectrum functionality, which can be enabled or disabled to reduce electromagnetic interference (EMI) emissions at the switching frequency. This feature is critical for meeting EMI compliance standards in automotive and industrial applications, ensuring reliable operation in noise-sensitive environments.
