The DRV591VFP from Texas Instruments is a high-efficiency, high-current PWM power driver. It is ideal for driving a wide variety of thermoelectric cooler elements and laser diode biasing applications. The device operates from a low supply voltage range of 2.8 V to 5.5 V, significantly reducing power dissipation and heat generation due to its PWM operation and low output stage on-resistance.
Key features include ±3-A maximum output current, over-current and thermal protection, and fault indicators for over-current, thermal, and under-voltage conditions. The junction temperature fault indicator signals around 130°C, allowing for system-level shutdown before internal thermal shutdown circuitry activates. The PWM switching frequency can be selected between 100 kHz and 500 kHz to meet system requirements. The gain is fixed at approximately 2.3 V/V, eliminating the need for external components.
This power driver is available in a 32-HLQFP Exposed Pad package, measuring 9 mm × 9 mm, and is designed for surface mount applications. Its robust protection features and efficient operation make it suitable for demanding power management tasks.
