Texas Instruments DRV8874 User Manual

DRV8876/74 Evaluation Module
This document is provided with the DRV887x family customer evaluation modules (EVM) as a supplement
to the DRV8876, DRV8876-Q1, DRV8874, and
hardware implementation of the EVM.
Hot surface. Contact may cause burns. Do not Touch.
DRV8876EVM and DRV8876-Q1EVM are rated for power supply voltages
between 4.5 VDC and 37 VDC max. The components can support peak output
currents up to a maximum of 3.5 ADC. To maintain component temperatures
below the 130°C rating of the printed circuit board material, TI requires that the
continuous current of both channels be limited to 1.7 ADC (each) when
operating for extended periods of time at an ambient temperature of 25°C.
DRV8874EVM and DRV8874-Q1EVM are rated for power supply voltages
between 4.5 VDC and 37 VDC max. The components can support peak output
currents up to a maximum of 6 ADC. To maintain component temperatures
below the 130°C rating of the printed circuit board material, TI requires that the
continuous current of both channels be limited to 3.3 ADC (each) when
operating for extended periods of time at an ambient temperature of 25°C.
