What are the key features of MAX20331EWL+?
- Single-channel 3.5 mm audio line overvoltage protection supporting transient voltages up to ±30 V, safeguarding audio circuitry from ESD and connector insertion events
- 9-bump WLCSP (wafer-level chip-scale package) measuring under 1.2 mm × 1.2 mm for ultra-compact PCB integration in smartphones and wearables
- Under/overvoltage supervisor function with no external resistors required — fixed threshold simplifies design and reduces BOM components
What is MAX20331EWL+ used for?
The MAX20331EWL+ is designed to protect 3.5 mm audio jack circuitry in smartphones, tablets, and portable media players from hazardous overvoltage events caused by ESD, connector hotplug, or accidental connection to high-voltage sources up to ±30 V. Its WLCSP package suits placement directly adjacent to the audio jack on space-constrained mobile PCBs. The device is also applicable in headset amplifiers and hearing instruments where audio line protection is mandated.

Frequently Asked Questions
What overvoltage level can the MAX20331EWL+ withstand on a 3.5 mm audio line?
The MAX20331EWL+ protects 3.5 mm audio lines against transient overvoltage events up to ±30 V, clamping hazardous potentials before they reach the audio codec or amplifier IC, ensuring circuit protection from accidental high-voltage connector contact in smartphones and portable devices.
How small is the MAX20331EWL+ package, and why does that matter for mobile PCB design?
The MAX20331EWL+ uses a 9-bump WLCSP package with dimensions under 1.2 mm × 1.2 mm, enabling placement within 1 mm of the audio connector on the PCB. This ultra-compact footprint is critical in smartphones and wearables where every square millimeter of board area is constrained.
Does the MAX20331EWL+ require external threshold-setting resistors to configure the overvoltage trip point?
No, the MAX20331EWL+ uses fixed internal thresholds for both under-voltage and overvoltage supervision — no external resistors are needed. This fixed-threshold architecture reduces the 3.5 mm audio line protection BOM to a single 9-bump WLCSP IC, saving design time and assembly cost.
In which consumer products is the MAX20331EWL+ audio line OVP IC typically used?
The MAX20331EWL+ is commonly specified in smartphones, tablets, wireless earbuds, and portable media players with 3.5 mm audio jacks. It is also used in hearing instruments and headset amplifiers where IEC 61000-4-2 ESD protection and accidental overvoltage protection of up to ±30 V is required on audio signal lines.
