Highway 09 Ic Datasheet ~repack~ Jun 2026

⚠️ Several electronic component distributors have incorrectly listed the HIGHWAY09A as a voltage regulator. This is a persistent error; the device is definitively a microcontroller, not a power management IC.

: Stable 5V DC output, pushing up to 1A max load. Quiescent Current ( IQcap I sub cap Q ) : Extremely low 10 A, optimizing standby modes.

: A Digital Switch Memory Interface capable of routing slots across 16 incoming PCM highways. MB6020A Series : Single-chip PCM codecs from that use highway-style serial interfaces. Am79C02/3 (DSLAC)

The reveals a versatile, rugged linear regulator suitable for a wide range of power supply applications. Its combination of high input voltage tolerance, low dropout, and thermal protection makes it a reliable choice for automotive, industrial, and consumer electronics.

Typical values at VIN = 12V, I_OUT = 500mA, T_A = 25°C, unless otherwise noted.

A: For output current above 500mA with a voltage drop of more than 5V, yes. Calculate power: P = (VIN – VOUT) × IOUT. If P > 1W, use a heatsink.

This article compiles the most accurate, aggregated datasheet information for the Highway 09 IC based on available technical references, reverse engineering reports, and application notes. Engineers and hobbyists working on vehicle LED retrofits, DRL (Daytime Running Light) controllers, or industrial high-bay lighting will find this guide essential.

According to the Highway09A Electrical Specification Sheet , the chip is built on a resilient CMOS processing substrate that minimizes quiescent battery/line drain while preserving signal performance in extremely noisy environments: HIGHWAY09A | In Stock - UTSOURCE.net Quiescent Current ( IQcap I sub cap Q

Understanding the Highway09 IC: The "Brain" of Modern Induction Cookers

For long-distance network segments (exceeding 10 meters), parallel termination resistors matching the characteristic impedance of the cable ( ) must be placed across the

Utilized in satellite receivers and networking equipment to manage real-time signal broadcasts. Engineering Considerations

A: No. The pinout is different. The 7805 has Input-Ground-Output, while the Highway 09 (TO-220) has Input-Ground-Output but note that the tab is also ground. Always check. Am79C02/3 (DSLAC) The reveals a versatile, rugged linear

The central reference ground point for both the internal digital sub-systems and the analog bus interface circuits. 4. Electrical Characteristics

Here is a breakdown of the critical features found within this essential document.

The HIGHWAY09A's exact pinout is considered proprietary, and an official datasheet is not publicly available. However, analysis of the Midea TM-S1-01W-A circuit board has revealed the pin functions. Here is a practical pinout based on that repair-focused analysis:
