CS40L25B-DNZR

Specialized ICS Overview

The CS40L25B-DNZR is a haptics driver integrating a Halo Core DSP and Class H boost converter. It supports LRA and VCM actuators with closed-loop control for resonance awareness and over-excursion protection. Key electrical parameters include an amplifier supply voltage of 11 V, compatibility with LRAs as low as 6 Ω, and < 20 µA AoH hibernation current. The device features a 32-QFN (5x5) package, operates from -40°C to +85°C, and provides real-time motor control with less than 5 ms wakeup latency.

Specialized ICS Feature Summary

• Integrated Halo Core DSP and Class H boost converter for high-efficiency actuator drive
• Closed-loop algorithms ensure consistent performance and protect LRAs from over-excursion
• Supports virtual button replacement and audio-to-haptics applications via I2C/GPI triggers
• Low power consumption with < 20 µA hibernation current and 5 ms wakeup time

Specialized ICS Applications

• Virtual button clicks and side button switch replacement
• Smartphones and wearable devices requiring precise haptic feedback
• Gaming controllers and automotive interfaces
• PC and consumer electronics with localized haptics

Specialized ICS Procurement Notes

Verify the specific ordering suffix DNZR against official documentation to confirm package type and availability status. Check for end-of-life or not-recommended-for-new-design notices. Confirm RoHS compliance and lead times with authorized distributors prior to procurement.

Specialized ICS Selection Notes

Select this component for applications requiring integrated DSP-based haptics without external microcontroller processing. Ensure the design accommodates the 32-QFN exposed pad thermal requirements. Verify that the target application supports the required I2C or GPI trigger interfaces for waveform activation.

Specialized ICS Part Context

This part belongs to the CS40L25/CS40L25B family of boosted haptics drivers. The CS40L25 variant supports GPIO + I2S at power-up, while the CS40L25B supports four GPIOs at power-up. Both share the same core DSP and driver architecture but differ in interface capabilities and package options.

Specialized ICS Replacement Considerations

Direct replacements within the family include CS40L25-CWZR and CS40L25B-CWZR for WLCSP packages. Cross-package substitution requires verification of pinout compatibility and thermal management strategies due to the difference between QFN and WLCSP form factors.
