The DRV590DWP is a high-efficiency PWM power driver from Texas Instruments, ideal for driving thermoelectric cooler elements and laser diode biasing. It operates within a supply voltage range of 2.7 V to 5.5 V, significantly reducing power dissipation through its PWM operation and low output stage on-resistance.
Key features include internal over-temperature protection, which activates at 190 °C and deactivates below 130 °C, and short-circuit protection that automatically resets the amplifier after 3–5 ms. The device supports adjustable gain configurations of 6, 12, 18, and 23.5 dB, controlled by GAIN1 and GAIN0 input terminals.
This power driver is available in a 20-SOIC package with an exposed pad, designed for surface mounting. It offers an output current of up to 1.22 A (82% duty cycle) and 1 A (100% duty cycle) at junction temperatures up to 89 °C. The operating temperature range is -40 °C to 85 °C, making it suitable for a variety of environmental conditions.
