DRV592-+-3 High Efficiency H-Bridge
Description The DRV592 is a high-efficiency, high-current H-bridge ideal for driving a wide variety of thermoelectric cooler-powered system elements from 2.8 V to 5.5 V. Low output stage on-resistance amplifiers significantly reduce power dissipation .
The DRV592 can drive the generator from any external PWM, such as a digital signal processor, microcontroller or FPGA. Frequency may vary from DC (ie on or off) to 1 MHz. This input is compatible with TTL logic levels. The DRV592 is internally protected from thermal and current overload. A logic-level signal fault indicator activates when the junction temperature reaches approximately 130°C to allow system-level shutdown before the amplifier's internal thermal shutdown circuit. The fault indicator also signals when an overcurrent event occurs. If the overcurrent circuit is triggered, the DRV592 automatically resets.
Features Halogen's 3-A maximum output current requires external PWM from DC to 1MHz with high and TTL compatible voltages Low operating voltage: 2.8 V to 5.5 V
High efficiency produces less heat Overcurrent and thermal protection fault indicator for overcurrent, thermal and undervoltage conditions
