Q & A
- What is the input voltage supply range for the TPIC6C596PWRG4?
The input voltage supply range is from 4.5 V to 5.5 V. - What type of outputs does the TPIC6C596PWRG4 have?
The device has low-side, open-drain DMOS transistor outputs. - What is the maximum current limit per output at 25°C?
The maximum current limit per output is 250 mA at 25°C. - What is the ESD protection rating of the TPIC6C596PWRG4?
The device provides up to 2500 V of ESD protection. - What is the operating temperature range of the TPIC6C596PWRG4?
The operating temperature range is from −40°C to 125°C. - How can multiple TPIC6C596PWRG4 devices be cascaded?
Multiple devices can be cascaded by connecting the serial output (SER OUT) of one device to the serial input (SER IN) of the next device. - What is the purpose of the output enable (G) pin?
The output enable (G) pin controls the output buffers; when G is low, data from the storage register is transparent to the output buffers. - How are the registers cleared in the TPIC6C596PWRG4?
All registers are cleared by setting the shift register clear (CLR) pin low. - What types of loads can the TPIC6C596PWRG4 drive?
The device can drive resistive and inductive loads, such as LEDs, lamps, relays, and solenoids. - What is the significance of the serial output (SER OUT) being clocked on the falling edge of SRCK?
This provides additional hold time for cascaded applications, improving performance in systems with skewed clock signals or electromagnetic interference.
