Description for the DRV594

The DRV593 and DRV594 are high-efficiency, high-current power amplifiers ideal for driving a wide variety of thermoelectric cooler elements in systems powered from 2.8 V to 5.5 V. The operation of the device requires only one inductor and capacitor for the output filter, saving significant printed-circuit board area. Pulse-width modulation (PWM) operation and low output stage on-resistance significantly decrease power dissipation in the amplifier.

The DRV593 and DRV594 are internally protected against thermal and current overloads. Logic-level fault indicators signal when the junction temperature has reached approximately 128°C to allow for system-level shutdown before the amplifier’s internal thermal shutdown circuitry activates. The fault indicators also signal when an overcurrent event has occurred. If the overcurrent circuitry is tripped, the devices automatically reset (see application information section for more details).

The PWM switching frequency may be set to 500 kHz or 100 kHz depending on system requirements. To eliminate external components, the gain is fixed at 2.3 V/V for the DRV593. For the DRV594, the gain is fixed at 14.5 V/V.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
