L6451013TR - 28-Channel Inkjet Driver, 5.25 V | STMicroelectronics
MPN: L6451013TR ✓ ActiveL6451013TR Overview
An inkjet driver is a specialized interface IC that converts low-voltage logic commands into controlled high-voltage and high-current drive signals for piezoelectric inkjet nozzles. In the system hierarchy, this device is a printer-specific peripheral driver within the broader interface IC and power-driver categories. Its 28 output channels allow one controller to manage multiple print-head elements while reducing the number of discrete drivers required at the board level.
The L6451013TR is listed as a 28-channel driver with a nominal peak output current limit of 2 A and a maximum supply voltage rating of 5.25 V. The 44-terminal PLCC package provides the mechanical footprint used in the original inkjet-printer controller boards. The commercial temperature range supports operation in controlled indoor printer and imaging environments, but the 0°C to 70°C limit is a key constraint for designs operating across wider industrial temperature ranges.
Typical applications include inkjet print-head carriage electronics, multi-nozzle print-head assemblies, printer engine control boards, and specialized inkjet dispensing systems. Because it is a dedicated 28-channel print-head driver rather than a general-purpose logic buffer, its timing inputs, protection features, and pin functions are intended for a particular inkjet drive architecture.
The principal design consideration is the relationship between the 2 A nominal peak output current rating, the inductive or capacitive load presented by the print head, and the protection network connected to each channel. PCB routing must minimize loop area in high-current drive paths, and unused or reserved outputs should be handled according to the manufacturer pin-description table. Production quantities should be confirmed before layout release because this is an older specialized printer-driver family with limited channel-count substitution.
This page consolidates package, channel-count, supply, temperature, and output-current information into a structured engineering reference. It also distinguishes the documented L6451013TR ratings from specifications that must be taken directly from the manufacturer datasheet, including precise channel timing, dropout behavior, and protection thresholds.

Typical Applications
L6451013TR is suitable for 6 applications: Inkjet Print-Head Driver Electronics, Piezoelectric Nozzle Drive Circuits, Multi-Nozzle Printer Controller Boards, Industrial Inkjet Dispensing Systems, Printer Engine Peripheral Control, Legacy Print-Engine Electronics Refresh.
Inkjet Print-Head Driver Electronics
The L6451013TR is designed for the drive stage of an inkjet print head because its 28 outputs can control multiple piezoelectric nozzle elements from a single 44-lead PLCC device. The documented 2 A nominal peak output current supports high-current switching demanded by print-head loads, while the 4.75 V to 5.25 V supply range matches low-voltage printer control electronics. Place the driver near the print-head connector, use short output paths, and verify channel timing and voltage limits against the manufacturer datasheet before layout release.
Recommended
Piezoelectric Nozzle Drive Circuits
A 28-channel inkjet driver is especially relevant to piezoelectric print heads, where each nozzle element requires controlled high-voltage pulses and precise timing. The L6451013TR's 2 A nominal peak output rating provides the drive-current class commonly needed by such loads without implying continuous 2 A per channel. Its 0°C to 70°C commercial range suits enclosed printer mechanisms, and the 44-lead PLCC package simplifies assembly on legacy print-engine controller boards.
Recommended
Multi-Nozzle Printer Controller Boards
The L6451013TR can reduce the number of discrete drive components required on a multi-nozzle printer controller by providing 28 dedicated channels in one package. This consolidation supports cleaner control-board layouts while retaining the specialized drive behavior expected by inkjet heads. Designers should verify whether each nozzle requires complementary drive, determine the maximum simultaneous switching count, and keep high-current loops compact around the driver and print-head connector.
Recommended
Industrial Inkjet Dispensing Systems
Specialized inkjet dispensers that deposit precise droplets onto a controlled surface can use the 28-channel architecture of the L6451013TR, provided the print head is electrically compatible with its drive timing and output ratings. The 4.75 V to 5.25 V supply range integrates well with printer logic, while the 2 A peak current specification supports the switching class of suitable nozzle loads. Confirm ambient conditions because the commercial 0°C to 70°C rating excludes colder factory environments.
Recommended
Printer Engine Peripheral Control
In an inkjet printer, the head driver works alongside motor, sensor, and engine-control circuitry, making the L6451013TR a natural choice for the dedicated print-head interface section of the controller. A 44-lead PLCC accommodates the channel outputs and associated control, supply, and ground connections in a compact surface-mount package. Keep logic-control routing away from the high-current outputs, provide local supply decoupling, and use the manufacturer pin table to identify every reserved terminal.
Recommended
Legacy Print-Engine Electronics Refresh
The L6451013TR can support a targeted refresh of an existing inkjet printer controller when its 44-lead PLCC footprint, 28-channel arrangement, and electrical drive requirements match the original design. The part is especially relevant to equipment that operates within 0°C to 70°C and uses a 4.75 V to 5.25 V control supply. Before substituting it into stored legacy hardware, compare pin functions, timing, output current, and protection characteristics against the exact board schematic.

Key Differentiators
- Dedicated 28-channel inkjet drive architecture (vs L6451012TR)
- Defined low-voltage supply operating window (vs L6451011TR)
- Published peak output current for load planning (vs L6451012TR)
Design Notes
Route the 28 high-current drive outputs as short, wide paths between the L6451013TR and the print-head connector. High-current switching loops should be kept away from logic and timing nets. Use a continuous ground reference beneath and around the device, and avoid routing sensitive control traces beneath the output paths. The 2 A peak rating describes output capability, not a continuous-current design target.
The documented supply range is 4.75 V to 5.25 V, so the controller must regulate the driver rail within that window rather than allowing rail droop during print-head switching. Place supply decoupling directly at the device's supply and ground pins and verify the regulator's transient response with the real print-head cable and load. Do not infer print-head output-voltage limits from the 5.25 V control-supply rating.
Do not select an alternative using package similarity alone. A valid replacement must match the 28 output channels, logic polarity, drive timing, output-stage voltage capability, and 2 A peak-current class. Because the commercial rating is limited to 0°C to 70°C, also confirm the enclosure temperature. Obtain manufacturer pin and timing tables before releasing a substitution into a production layout.
