The TPIC6C596D, manufactured by Texas Instruments, is a high-voltage, high-current integrated circuit that combines an 8-bit shift register with a Darlington transistor array. This device is designed to provide a convenient interface between microprocessors or microcontrollers and high-voltage/high-current loads, particularly where serial-to-parallel data conversion is required for driving LEDs, relays, or other similar loads.
Key Features
- Output Rating: The TPIC6C596D can handle up to 100 mA of continuous current per channel and up to 500 mA of peak current, making it suitable for driving a wide range of high-power devices.
- High Voltage: It is capable of withstanding output voltages up to 50V, providing the flexibility to control higher voltage applications.
- Serial Interface: The device includes a built-in 8-bit serial-in, parallel-out shift register that allows for serial input data to be transferred into each output latch on the rising edge of the clock signal.
- Power Clamp: Each output of the TPIC6C596D features a clamp diode for inductive transient suppression, which is ideal for inductive loads such as relays and solenoids.
- Low Power Consumption: The IC has a low ON-state resistance, reducing power dissipation and making it more energy-efficient for applications.
Applications
The TPIC6C596D is commonly used in a variety of applications that require the direct control of high-voltage or high-current loads. These include:
- LED displays and signage
- Relay drivers
