Product details
Overview
DRV201AYMBRB from Texas Instruments is a voice coil motor (VCM) driver IC designed for camera auto-focus systems. It integrates a 10-bit DAC, PWM/linear mode selection, advanced ringing compensation, and I²C interface (400 kHz). It delivers up to 102.3 mA output current with ±10 LSB relative accuracy and operates from 2.5 V to 4.8 V supply voltage in mobile phone and digital still camera modules.
For engineers reviewing the DRV201AYMBRB datasheet, DRV201AYMBRB pinout, DRV201AYMBRB application, or DRV201AYMBRB equivalent, key selection considerations include its 6-ball PicoStar WCSP package, integrated open/short-circuit detection, thermal shutdown at 140°C, 4-kV HBM ESD rating, and support for VCM resonance frequency tuning from 50 Hz to 150 Hz via register 07h.
Technical Context
The DRV201AYMBRB implements a half-bridge PWM driver or high-side linear current source, selectable via the MODE register's PWM/LIN bit. Current regulation uses an internal 1-Ω sense resistor and error amplifier referenced to the 10-bit DAC output. Switching frequency is programmable from 0.5 MHz to 4 MHz through the CONTROL register.
Ringing compensation generates optimized current ramps based on user-configured VCM resonance frequency (50–150 Hz), tolerating ±10% variation with 1/fVCM mode or ±30% with 2/fVCM mode. Fault protection includes undervoltage lockout (2.0 V falling / 2.2 V rising), overtemperature shutdown (140°C), and VCM open/short detection triggered at ≥256 mA code.

| VCM open/short detection | Uses dedicated current threshold (≥256 mA code) and status flag to identify faulty actuators before deployment - improves field reliability and diagnostic capability. |
| 4-kV HBM ESD protection | Ensures robustness against electrostatic discharge during board assembly and module integration without requiring external TVS devices. |
Applications
| Cell Phone Auto Focus | Digital Still Camera Auto Focus |
|---|---|
Use Scenario: Compact smartphone rear/front camera modules requiring fast, silent, and repeatable lens movement for real-time autofocus. IC Role / Device Role / Timing Role: Primary VCM current controller; receives I²C commands from ISP to set target position; executes ringing-compensated current ramp. Use Value: Achieves sub-20-ms lens settling (±10% error band) using 1/fVCM compensation - critical for burst capture and video AF responsiveness. |

| Security Cameras | Web and PC Cameras |
Use Scenario: Outdoor IP cameras with wide temperature range (-40°C to +85°C) and long-term reliability requirements. IC Role / Device Role / Timing Role: VCM driver with integrated fault protection; monitors VCM continuity and junction temperature autonomously. Use Value: Thermal shutdown at 140°C and open/short detection prevent catastrophic failure during extended operation in unventilated enclosures. |
Use Scenario: USB-based webcams and conferencing devices where board space and BOM count are tightly constrained. IC Role / Device Role / Timing Role: Single-chip VCM solution replacing discrete MOSFETs, op-amps, and DACs; reduces component count by ≥5 parts. Use Value: 0.3-mm max package height and 0.80 mm × 1.48 mm footprint enable placement directly beneath lens barrels - minimizing trace inductance and EMI. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voice coil motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI DRV2011YMBR | Same 6-ball PicoStar package and pinout; lower max output current (75 mA); no 2/fVCM ringing compensation mode. | Suitable for lower-power VCMs (e.g., <15 Ω, <100 µH); lacks extended resonance tolerance for high-mass lens stacks. | Select DRV2011YMBR only when VCM current demand is ≤75 mA and resonance stability is >±10% - avoids over-spec'ing cost and complexity. |
| ROHM BU3903KV | 8-pin WLCSP; 12-bit DAC; fixed 1.8-V I/O; no programmable switching frequency; 3.3-V max VBAT. | Requires level-shifting for 3.3-V I²C buses; limited supply headroom for aging batteries; higher resolution but less flexible compensation. | Prefer BU3903KV only when 12-bit precision is mandatory and system operates strictly within 1.8-V I/O and 3.3-V supply constraints. |
Compared with DRV201AYMBRB, DRV2011YMBR offers identical form factor but reduced drive strength and compensation flexibility, while BU3903KV trades package compatibility and supply range for higher DAC resolution - making DRV201AYMBRB the optimal balance of performance, protection, and design margin for mainstream mobile autofocus.

FAQ
What is the maximum VCM current supported by the DRV201AYMBRB?
The DRV201AYMBRB supports a maximum output current of 102.3 mA, corresponding to the full-scale code (1023) of its integrated 10-bit DAC. This value is confirmed in the Electrical Characteristics table under "IMAX" and is achievable across the full operating temperature range when supplied with ≥3.7 V and using appropriate PCB thermal design.
How does the DRV201AYMBRB implement ringing compensation?
The DRV201AYMBRB implements ringing compensation by generating optimized current ramp profiles based on the VCM resonance frequency programmed into register 07h (VCM_FREQ). Users configure this register for frequencies from 50 Hz to 150 Hz in 1-Hz steps. The device then applies either 1/fVCM or 2/fVCM compensation, tolerating ±10% or ±30% resonance variation respectively - reducing lens settling time significantly versus open-loop control.
What package type is used for the DRV201AYMBRB?
The DRV201AYMBRB uses a 6-ball PicoStar wafer-level chip-scale package (WCSP) with 0.4-mm pitch, nominal body size of 0.80 mm × 1.48 mm, and maximum height of 0.3 mm. This package is explicitly listed in the Device Information table of the datasheet and is optimized for ultra-thin camera module integration.
Does the DRV201AYMBRB support both PWM and linear driving modes?
Yes, the DRV201AYMBRB supports both PWM and linear VCM driving modes. Mode selection is controlled via the PWM/LIN bit in the MODE register (address 01h). In linear mode, the high-side PMOS operates as a current source; in PWM mode, it functions as a half-bridge switch with programmable frequency (0.5–4 MHz) - enabling trade-offs between efficiency and acoustic noise.
What fault protections are built into the DRV201AYMBRB?
The DRV201AYMBRB includes open-circuit and short-circuit detection for the VCM, undervoltage lockout (UVLO) with 2.0 V falling / 2.2 V rising thresholds, thermal shutdown at 140°C, internal current limiting, and 4-kV HBM ESD protection on all pins. These protections are documented in Sections 1 and 3 of the datasheet and operate autonomously without host intervention.
