What are the key features of TPIC46L03DBRG4?
- 6-channel low-side pre-FET driver with serial and parallel interface for flexible MCU integration
- Standard CMOS/TTL-compatible inputs simplify direct connection to 3.3 V and 5 V logic controllers
- 28-pin SOIC (R-PDSO-G28) package with 1.2 mA output current limiting per channel for safe MOSFET gate drive
What is TPIC46L03DBRG4 used for?
The TPIC46L03DBRG4 is designed for low-side MOSFET gate driving in industrial relay arrays, LED matrix drivers, and solenoid control circuits where 6 independent channels must be managed via a serial interface. Its pre-FET architecture reduces the current demand on the MCU GPIO pins, making it practical for battery-powered IoT nodes and automation equipment with limited drive capability. The 28-pin SOIC footprint fits standard PCB layouts and supports automated assembly for high-volume production.

Frequently Asked Questions
How many channels does the TPIC46L03DBRG4 provide and what output current can each channel drive?
The TPIC46L03DBRG4 integrates 6 independent low-side driver channels, each with a nominal peak output current limit of 1.2 mA. This makes the device suitable for driving MOSFET gates in relay, solenoid, or LED applications where moderate sink current per channel is sufficient.
Can TPIC46L03DBRG4 interface directly with a 3.3 V MCU for a 6-channel motor relay board?
Yes, the TPIC46L03DBRG4 accepts standard CMOS and TTL logic inputs compatible with both 3.3 V and 5 V microcontrollers. The serial/parallel interface allows daisy-chaining multiple devices, enabling a single SPI bus to control more than 6 channels without additional GPIO pins on the host MCU.
What package does the TPIC46L03DBRG4 use and how does it affect PCB layout density?
The TPIC46L03DBRG4 is housed in a 28-pin Small Outline package (SOIC, JESD-30 code R-PDSO-G28), offering a compact surface-mount footprint. Compared to a 28-pin DIP, the SOIC saves significant board area and supports reflow soldering, which is advantageous in high-density industrial control PCBs.
Is TPIC46L03DBRG4 RoHS compliant and what does its JESD-609 code indicate?
The TPIC46L03DBRG4 carries JESD-609 code e4, indicating lead-free termination plating per the JESD-609 standard. However, the Pbfree Code is listed as No in some data records, so designers should verify the specific lot marking or contact Texas Instruments to confirm full RoHS compliance for their production BOM before ordering in volume.
