TPIC6595DW

Description of TPIC6595DW

The TPIC6595 is an 8-bit shift register that is monolithic, high-voltage, and high current power and was created for use in systems that need a lot of load power.

For protection against inductive transients, the device has a built-in voltage clamp on the outputs. Relays, solenoids, and other moderate or high-voltage loads are examples of power driver applications.

TPIC6595DW is an 8-bit D-type storage register is fed via an 8-bit serial-in, parallel-out shift register in this device. On the rising edge of the shift-register clock (SRCK) and the register clock (RCK), respectively, data passes through both the shift and store registers.

Transfers occur in the storage register.

As soon as shift register clear (SRCLR) is high, data is sent to the output buffer. The input shift register is reset when SRCLR is low. All data in the output buffers is held low and all drain outputs are turned off when output enable (G) is maintained high. Data from the retention register is invisible to the output buffers when G is kept low.

The shift register’s data can be cascaded to multiple devices via the serial output (SER OUT). Low-side, open-drain DMOS transistors with output ratings of 45 V and continuous sink current capabilities of 250 mA are used as the outputs.

The DMOS-transistor outputs are off when there is little data in the output buffers. The DMOS-transistor outputs have the capacity to sink current when data is high.
