PWM operation and low output stage on-resistance significantly decrease power dissipation in the amplifier. The DRV590 is internally protected against over temperature conditions and current overloads due to short circuits. The over temperature protection activates at a junction temperature of 190 °C and will deactivate once the temperature is less than 130 °C. If the overcurrent circuitry is tripped, the amplifier will automatically reset after 3–5 ms. The gain of the DRV590 is controlled by two input terminals, GAIN1 and GAIN0. The amplifier may be configured for a gain of 6, 12, 18, and 23.5 dB.
