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.
