TPIC2810D集成电路（IC）的LED驱动器规格书PDF中文资料

TPIC2810D属于集成电路（IC）的LED驱动器。由德州仪器制造生产的TPIC2810DLED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。

description

The TPIC2810 device is a monolithic, mediumvoltage,

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.
