Overview
The TPIC6B595DWRG4 is a monolithic, high-voltage, medium-current power 8-bit shift register designed by Texas Instruments. This device is tailored for use in systems that require relatively high load power, such as automotive relay and solenoid drivers, and other medium-current or high-voltage loads. It features an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register, enabling efficient data transfer and control.

Key Features
- 8-Bit Serial-In, Parallel-Out Shift Register: Feeds an 8-bit D-type storage register, allowing for efficient data transfer and control.
- High-Voltage and Medium-Current Capability: Each output is rated for 50 V and 150 mA continuous sink-current capability, with a typical current limit of 500 mA at TC = 25°C.
- Inductive Transient Protection: Built-in voltage clamp on the outputs for inductive transient protection.
- Cascadable: The serial output (SER OUT) allows for cascading of the data from the shift register to additional devices.
- Low Power Consumption: Designed for low power consumption, making it suitable for a variety of applications.
- Output Control: Output enable (G) allows for controlling the output buffers; holding G high keeps all data in the output buffers low, and all drain outputs are off.
- Clear Functionality: A logical low on the shift register clear (SRCLR) clears all registers in the device.
Applications
- Automotive Relay and Solenoid Drivers: Ideal for controlling relays and solenoids in automotive systems.
- Medium-Current or High-Voltage Loads: Suitable for driving other medium-current or high-voltage loads such as LEDs, motors, and more.
- Industrial Control Systems: Can be used in industrial control systems that require high load power and reliable operation.
- Consumer Electronics: Applicable in various consumer electronics that need high-current and high-voltage control.
Q & A
- What is the operating voltage range of the TPIC6B595DWRG4?
The operating voltage range is from 4.5 V to 5.5 V.
- What is the maximum continuous current per output channel?
The maximum continuous current per output channel is 150 mA.
- What is the output clamp voltage for inductive transient protection?
