Part Number:S11-3A-EMF-HBRIDGE
Price:$47.00 (USD)

This is a 3A H-Bridge Module based on the LMD 18200 H-Bridge. In addition, this bridge offers pass-through connections for quadrature encoders, fuse protection, and an innovative Back-EMF velocity measurement circuit.

Manufactured By - Acroname Inc.

This H-Bridge driver incorporates a Back-EMF measurement circuit that allows you to discern motor speed without an encoder. The bridge is based on the National 18200 H-Bridge chip so it has very low resistance (0.4Ω), and can handle currents of 3A continuously and as much as 6A surge. The pinout for this H-Bridge component conforms to the Acroname H-Bridge Standard.

Features

  • 3 Feedback Modes (Back-EMF, Current Sense, and Quadrature)
  • Drives loads up to 27.5V
  • 3 A continuous current
  • 6 A momentary peak current
  • PWM frequency from 39,000-500,000 Hz

Revision History:

  • February 17th, 2011 - Updated reference materials and Datasheet.
