Product details
Overview
A6B259KA from Allegro MicroSystems is a 8-bit addressable DMOS power driver for low-side peripheral load control. In systems that use A6B259KA, addressed output control rather than a pure serial shift-register update model. It fits boards that select one output path through address logic while still needing real switched-load capability.
For engineers reviewing the A6B259KA datasheet, A6B259KA pinout, A6B259KA application, or A6B259KA equivalent, this device is widely used in addressed peripheral load control, multiplexed output sections, low-side DMOS load-switch banks, and embedded power interface boards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Device Type | 8-bit addressable DMOS power driver. |
| Control Method | Addressable latch and demultiplexer-style control. |
| Output Count | Eight DMOS low-side outputs. |
| Output Voltage | 50 V class output capability. |
| Application Positioning | Addressed low-side load control for peripheral power outputs. |
| Package Option | 24-pin plastic DIP package with tube packing. |
| Ambient Temperature | -40°C to +85°C ambient range |
Pinout & Package
The A6B259KA pinout is implemented in the 24-pin plastic DIP package and combines the monitored-rail pins, control pins, and reset, watchdog, sequencing, or fault outputs required by the device function.
For PCB design, the main consideration is routing the control interface and power/load paths according to the actual device function instead of treating the part as a generic placeholder.
| Pin / Function | PCB Design and Circuit Role |
|---|---|
| Address Select Pins | Choose which output channel is addressed by the control logic. |
| Data / Enable / Clear | Control output storage, activation, and reset behavior. |
| Output Pins | Provide the eight DMOS low-side outputs. |
| Logic Supply | Powers the address and latch logic core. |
| Ground / Power Ground | Provide current return for both logic and output-drive sections. |
Key Features
- Addressable control supports one-of-many load selection.
- Eight DMOS outputs fit low-side switched peripheral loads.
- Useful when the controller uses address logic instead of a long serial word.
- Helps integrate decode and power-drive functions in one device.
Applications
| Addressed Load Banks | Multiplexed Peripheral Controls |
|---|---|
|
Use Scenario: Outputs selected by an address map. IC Role: Acts as the low-side addressed driver. Use Value: Reduces external decode and transistor count. |
Use Scenario: Load sections where one-of-many output selection is central. IC Role: Provides the addressed output stage. Use Value: Supports compact addressed-output hardware. |
| Legacy DMOS Output Boards | Embedded Power Interface Logic |
|
Use Scenario: Boards already expecting A6B259 family behavior. IC Role: Preserves the original control architecture. Use Value: Cuts redesign work in sustainment products. |
Use Scenario: Logic-level control switching peripheral loads. IC Role: Bridges address logic and output power handling. Use Value: Improves integration over discrete decode-plus-driver schemes. |
Equivalent & Alternatives
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A6B595KLWTR | Serial-input DMOS power-driver family rather than addressable-control family. | Better when the design wants shift-register-driven outputs. | Use only if the control architecture can move from addressed to serial. |
| A6841SLWTR-T | Latched sink-driver family with different output technology and control style. | Better for serially latched low-side loads, not address-selected outputs. | Do not substitute unless the control method changes too. |
Compared with A6B595KLWTR, A6B259KA selection depends on output count, output polarity, and package family. Compared with A6841SLWTR-T, A6B259KA is the better choice when the board needs the same drive architecture while keeping the surrounding serial-control or load-drive scheme.
Quality
A6B259KA should be sourced through traceable channels with attention to package identity, orderable suffix, and whether the replacement still matches the intended device role.
Production validation should include interface behavior, load-path performance, startup behavior, and thermal or protection checks that matter for the actual end application.
Availability
A6B259KA is available at Aetrix Electronics and is suitable for maintenance, new design qualification, and repeatable production support in systems that depend on this exact device role.
Sample and NPI supply support, as well as urgent in-stock supply support, can also be arranged for prototype builds, pilot runs, and time-critical production needs.
For production builds, confirming lifecycle position, package option, temperature range, and sourcing continuity helps reduce replacement risk.
Manufacturer
Allegro MicroSystems is a semiconductor manufacturer whose portfolio includes sensor, driver, interface, and power-management devices used across automotive, industrial, and embedded electronics.
The A6B259 line is an addressable DMOS power-driver family used where output selection is driven by address logic rather than a full serial output word.
FAQ
What is A6B259KA used for?
It is used as an addressable DMOS power driver for low-side peripheral loads.
Where can I find the A6B259KA datasheet download?
The A6B259KA datasheet can be accessed from the confirmed source used for this A6B259 orderable option.
What should be considered in A6B259KA pinout design?
Designers should review the 24-pin plastic DIP package, keep the control path clean, and plan the load-current routing and supply decoupling around the actual application role.
Is A6B259KA a voltage regulator?
Only if the device family is actually a regulator. Otherwise it should be treated as a driver or supervisor according to its real function.
What are common A6B259KA equivalent solutions?
Common candidates depend on package fit, temperature range, output structure, and whether the replacement preserves the same device role on the board.
