Q & A
- What is the primary function of the TPIC6C596DR?
The TPIC6C596DR is an 8-bit shift register designed to drive moderate load power devices such as LEDs, relays, and solenoids. - What is the operating temperature range of the TPIC6C596DR?
The device operates over a temperature range of -40°C to 125°C. - What is the maximum output voltage rating of the TPIC6C596DR?
The maximum output voltage rating is 33 V. - What is the continuous sink current capability per channel?
Each channel has a continuous sink current capability of 100 mA. - Does the TPIC6C596DR have ESD protection?
Yes, it provides up to 2500 V of ESD protection. - How does the device handle cascading?
The device allows for enhanced cascading by clocking the serial output (SER OUT) on the falling edge of the shift register clock (SRCK), providing additional hold time for cascaded applications. - What is the purpose of the built-in voltage clamp?
The built-in voltage clamp provides inductive transient protection. - How are the registers cleared in the TPIC6C596DR?
All registers are cleared by setting the shift register clear (CLR) input low. - What is the role of the output enable (G) pin?
Holding the output enable (G) pin low makes data from the storage register transparent to the output buffers, while holding it high keeps all data in the output buffers low and all drain outputs off. - Can the TPIC6C596DR be used for global PWM dimming?
Yes, the output enable (G) pin can also be used for global PWM dimming.
