Introduction

AI Translation

The DRV8434E/P is an integrated motor driver solution for bipolar stepper motors or dual brushed DC motors. These devices integrate two N-channel power MOSFET H-bridges, integrated current sensing and regulation circuits. The DRV8434E/P is pin-to-pin compatible with the DRV8426E/P, DRV8436E/P, and DRV8424E/P. The DRV8434E/P can be powered by a supply voltage from 4.5V to 48V and can provide an output current of up to 4A peak or 2.5A full-scale. The actual full-scale and RMS currents depend on the ambient temperature, supply voltage, and PCB thermal performance.

The DRV8434E/P devices use an integrated current sensing architecture, eliminating the need for two external power sense resistors. This significantly saves board space and BOM cost, reduces design effort, and significantly lowers power consumption. This architecture uses a current mirror approach and internal power MOSFETs for current sensing, eliminating power loss in the sense resistors. The current regulation setpoint is adjusted by the voltage at the VREFA and VREFB pins. Current regulation is highly configurable and can operate in multiple decay modes. Selectable decay modes include Smart Tune Dynamic Decay, Smart Tune Ripple Control, Mixed, or Fast Decay. The PWM off-time tOFF can be adjusted to 7, 16, 24, or 32μs. The system includes a low-power sleep mode to save power when the motor is not being driven.
