Highway 09 Ic Datasheet Jun 2026

The (often listed as HIGHWAY09A ) is a versatile integrated circuit manufactured by companies like Holtek and widely utilized in automotive, industrial, and consumer electronics. It is primarily recognized as a low-power microcontroller or signal processing IC designed for applications requiring precise control and efficient power management. Technical Specifications

A key point for induction cooker operation is the relationship between pins 4 and 15, which measure a voltage drop from the main power supply. This slight voltage differential (Va - Vb) is critical for the chip to perform "synchronous control" over the IGBT switching transistor, ensuring efficient power transfer without destroying the main switching element.

According to technical documentation and the Highway 09 IC Datasheet , the device typically operates within the following parameters: 2.4V to 5.5V. Operating Frequency: 32kHz to 8MHz.

| Parameter | Test Condition | Min | Typ | Max | Unit | |-----------|----------------|-----|-----|-----|------| | Output Voltage (Fixed 5V) | I_OUT = 10mA | 4.90 | 5.00 | 5.10 | V | | Line Regulation | VIN = 6V to 40V | | 0.01 | 0.05 | %/V | | Load Regulation | I_OUT = 10mA to 1.5A | | 0.1 | 0.5 | % | | Dropout Voltage | I_OUT = 1A | | 300 | 500 | mV | | Quiescent Current | I_OUT = 0mA | | 2.5 | 5.0 | mA | | Shutdown Current | EN = 0V | | 10 | 20 | µA | | Ripple Rejection (PSRR) | f = 120Hz | 60 | 75 | | dB | | Thermal Shutdown Temp | | 150 | 160 | 170 | °C |
