The TLC6A598 device is a monolithic, high-voltage, high-current power 8-bit shift register designed for use in systems that require relatively high load power, such as LEDs.

The device contains a built-in voltage clamp on the outputs for inductive transient protection. Power driver applications include relays, solenoids, and other high-current or high-voltage loads. Each open-drain DMOS transistor features an independent chopping current-limiting circuit to prevent damage in the case of a short circuit.

This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Outputs are low-side, open-drain DMOS transistors with output ratings of 50 V and 350-mA continuous sink-current capabilities. A built-in load open or load short diagnostic mechanism provides enhanced safety protection. The device provides a cycle redundancy check to verify register values in the shift registers. In read-back mode, the device provides 6 bits of the CRC remainder. The MCU can read back the CRC remainder and check if the remainder is correct to determine whether the communication loop between MCU and device is good.

The TLC6A598 characterization is for operation over the operating ambient temperature range of −55°C to 125°C.
