BD16938AEFV-CE2

Overview

The BD16938AEFV-CE2 is an automotive-grade, 8-channel half-bridge driver designed for brushed DC motor control. It features a 16-bit SPI interface for MCU communication and supports High, Low, and Hi-Z output modes. The device operates on a supply voltage range of 6.3 V to 32 V, with a maximum VCC of 40 V. It delivers up to 1 A output current per channel with a typical on-resistance of 1.4 Ω. Key electrical parameters include a standby current of 7 mA, an operating temperature range of -40°C to +125°C, and AEC-Q100 Grade 1 qualification. It is housed in a compact HTSSOP-B-28 package.

Feature Summary

• Supports independent three-mode output control (High, Low, and High Impedance) for each channel via SPI.
• Integrates comprehensive protection mechanisms including over-current, under-voltage lockout, thermal shutdown, and reverse voltage diodes.
• Optimized for low power consumption with built-in standby current reduction capabilities.
• Automotive qualified to AEC-Q100 standards for high reliability in harsh environments.

Applications

• Brushed DC motor drivers in automotive systems
• Stepper motor control applications
• Ignition system controllers
• Motion control modules requiring multiple half-bridge outputs

Procurement Notes

Verify the specific suffix 'CE2' against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure that the ordering part number matches the required automotive grade and functional safety support level. Cross-reference the pinout configuration with the target PCB layout to avoid compatibility issues during integration.

Selection Notes

Select this component when designing systems requiring direct drive of multiple brushed DC motors or stepper motors with minimal external components. The integrated SPI interface simplifies control logic compared to parallel interfaces. Consider the 1 A current capability and 32 V rating for appropriate load matching. Evaluate the thermal performance within the HTSSOP-B-28 package for the expected duty cycle and ambient conditions.
