1 / 23 page TPIC2810 8BIT LED DRIVER WITH I2C INTERFACE SLIS109A − DECEMBER 2001 − REVISED SEPTEMBER 2002 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Low rDS(on) ...5 Ω Typical D Eight Power DMOS Transistor Outputs of 100-mA Continuous Current D 210-mA Current Limit Capability D Drain Output ESD Protection . . . 3000 V D Output Clamp Voltage ...40 V description The TPIC2810 device is a monolithic, medium- voltage, low-current, 8-bit shift register design to drive low-side switched resistive loads such as LEDs. The device is not recommended for switching inductive loads. This device contains an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Data transfers through the shift register via an I2C bus interface. Data is transferred into the data shift register only after the group ID and device address have been verified. The subaddress directs the I2C bus interface to read or write data to the device or transfer data to the output. When output enable (G) is held high, all drain outputs are off. When G is held low, data from the output storage register is transparent to the output buffers. When data in the output buffers is low, the DMOS transistor outputs are off. When data is high, the DMOS transistor outputs have sink-current capability. The TPIC2810 device has an internal power-up clear to initialize all registers to an off state when power is applied to the device. It also has a thermal sensor to monitor the die temperature and shut the drain outputs off, if an over current condition occurs. Outputs are low-side, open-drain DMOS transistors with output ratings of 40 V and 100 mA continuous sink-current capability. Each output provides a 210-mA maximum current limit at TC = 25°C. The current limit decreases as the junction temperature increases for additional device protection. The device also provides up to 3000 V of ESD protection on output terminals and 2000 V of ESD protection on input terminals when tested using the human-body model. The TPIC2810 device is characterized for operation over the operating case temperature range of −40 °C to 125 °C.
