TPIC2810DR

TPIC2810DR is an 8‑channel constant‑current LED driver (sink) with a serial control interface. It lets a microcontroller drive eight LED strings with regulated current, set by an external resistor, and updated via a simple SPI‑like data stream (data, clock, latch). Each channel provides constant-current regulation, and dimming is achievable through the serial data stream (and optional dim/blanking controls). The device includes protection features such as open/short‑circuit handling and thermal shutdown to help prevent LED/string damage. The DR suffix simply denotes a Tape‑and‑Reel packaging variant. Typical uses include LED backlighting, displays, and signage where multiple LED strings need synchronized, controlled current. For exact current range, voltage, timing, and wiring, refer to the TPIC2810DR datasheet.

Direct drop-in equivalents for TPIC2810DR don’t exist. Closest cross-references are:
- ULN2803A (8-channel Darlington sink) from TI for similar low-side switching
- ULN2003A (7-channel) for similar use
- TPIC6B595 (8-bit serial-to-parallel LED/solenoid driver) if a shift-register interface is acceptable
For an exact substitute, provide your supply voltage, per-channel current, package, and switching requirements to tailor a replacement.

Key features of TPIC2810DR (typical):
- 8-channel constant-current LED sink driver
- Outputs are open-collector/open-drain and sink current from LED strings
- External resistor sets the current per channel
- Wide operating voltage (suitable for common LED string voltages)
- PWM/dimming capability for brightness control
- Built-in protection: overcurrent/short-circuit and thermal shutdown
- Good current balancing across channels
- Packaging options including DR (Tape & Reel) variants; standard automotive/industrial packaging often available
Note: For exact current ranges, voltage limits, and pinout, please refer to the official datasheet.

Pin count: 22 pins (DIP-22/SO-22).
Function: TPIC2810DR is a 10-channel high-current open-collector sink driver (Darlington-type) array. It provides 10 input pins (IN1–IN10) and 10 corresponding outputs (OUT1–OUT10) to sink loads to ground, with a common ground and a COM/diode pin for inductive loads. Used to drive LED strings or similar loads by sinking current.
