RE: DRV595: Increasing power capability
Hi Anders, 7.5A over-current protect threshold is for an instantaneous signal. When the output current exceeds the threshold, OC FAULT is triggered. But 4A maximum output is more for thermal...

Based on the thermal resistance JA 22 deg/W, 85 degC environment and the thermal trip point 150 degC I get a dissipation of 2.95W in the device. Assuming your rough 4A is valid I then get a rdson of...

Hello Rick-san, Thank you for your prompt reply. Looking at the electrical specification, VIH_MAX is 0.5 x VCC. So when VCC=6.0V, VIH_MAX = 3.0V. If 3.3V is acceptable, what is the meaning of "VIH_MAX"...
