Low-side 8-Bit Shift Register for driving high voltage, medium current devices.
DESCRIPTION
The TPIC6B595 is a low-side 8-Bit Shift Register useful for driving high voltage, medium current common anode 7-Segment displays and other devices.
PACKAGE INCLUDES:
- TPIC6B595 High Power 8-Bit Shift Register
KEY FEATURES OF TPIC6B595 HIGH POWER 8-BIT SHIFT REGISTER:
- Used to expand output I/O capability of uC to drive high power devices
- 8-Bit Serial In / Parallel Out
- Low-side operation
- 50V @ 150mA drive capability
- Low on state resistance of 5 ohm typical
- 5V compatible
The TPIC6B595 is similar in functionality to the common 74HC595 except each output latch has a DMOS transistor that can sink up to 150mA continuous at up to 50V so it can directly handle high power loads. Do take note that the package size and pinout of the TPIC6B595 is different than the 74HC595 if replacing one with the other.
Since it is designed to sink current it can operate on the low side of loads. It is particularly well suited for driving larger high voltage common anode 7-segment or other LED displays but can also drive relays and similar loads. It has built-in suppression diodes to protect against inductive load transients.
Data is shifted in serially and then latched on the chips 8 output pins in parallel. Multiple chips can be daisy-chained together if more outputs are needed.
A single channel can handle up to a maximum of 50V@500mA. The maximum per channel overall will depend on how many channels are being used and the duty cycle that the channel is being switched at.
The part can operate from 4.5- 5.5V on the logic supply and up to 50V on the load supply and is 5V logic compatible.
These parts are the DIP version so they are breadboard friendly.
OUR EVALUATION RESULTS:
These parts make using high voltage common anode 7-segment displays easy. They can replace the typical 74HC595 and separate power drivers.
Be sure to use the appropriate size series current limiting resistors if using it to drive LEDs.
