The TPIC6259 from Texas Instruments is a monolithic, high-voltage, high-current power logic 8-bit shift register designed for use in systems that require relatively moderate load power such as LEDs, relays, and solenoids. This integrated circuit (IC) combines the functionality of an 8-bit shift register and output latches with 8 low-side MOSFET output drivers, offering a compact and efficient solution for controlling multiple outputs in your electronic designs.
Key Features:
- Integrated Power Output Stage: The TPIC6259 integrates an 8-bit serial-to-parallel shift register with a high current output stage, capable of sinking up to 250 mA per channel. The total package can sink up to 500 mA, making it suitable for driving a wide array of loads.
- Enhanced Thermal Performance: The IC is designed with a thermal shutdown feature that protects the device from overheating. This ensures reliable operation and a longer lifespan even under high current driving conditions.
- Flexible Voltage Operation: It operates over a wide supply voltage range from 4.5V to 5.5V, making it versatile for various applications and compatible with standard logic families.
- Robust Output Protection: Each output is equipped with clamp diodes for inductive transient suppression, which is essential when driving inductive loads such as relays and motors.
- Simple Serial Interface: The serial input can be driven by standard microcontrollers, allowing for easy integration into your digital control system. The serial output allows for cascading multiple TPIC6259 devices for extended input/output (I/O) applications without requiring additional I/O pins on the microcontroller.
