SineMicro Products

SineMicro offers four main product categories: 1) Automotive MCUs - AEC-Q100 certified microcontrollers for body control, lighting, and motor drive applications. Ideal for turn signals, window controls, and seat controllers. 2) Power Management ICs - High-voltage LDOs and PMICs for automotive power supply applications. Suitable for powering sensors, MCUs, and communication modules. 3) Power Devices - Automotive-grade MOSFETs and IGBTs for power switching and motor control. Used in LED drivers, motor drives, and power distribution. 4) Integrated Solutions - MCU+Power combinations for complete system solutions. Selection depends on your specific application requirements, voltage/current needs, and system architecture. Contact our FAE team for detailed product selection guidance.

Identify your application requirements first, then select the appropriate product category. Contact FAE for detailed selection support.

SineMicro ASM87 and ASM30 series serve different application needs: ASM87 Series - General-purpose automotive MCUs optimized for body control applications. Features include: 8-bit or 32-bit cores, integrated ADCs, PWM outputs, CAN/LIN interfaces, wide operating voltage range (2.7V-5.5V), and extended temperature range (-40°C to +125°C). Best for: turn signal controllers, window lift modules, door control modules, and seat controllers. ASM30 Series - Motor control optimized MCUs with enhanced features for motor drive applications. Features include: dedicated motor control peripherals, high-resolution PWM, integrated gate drivers, current sensing amplifiers, and advanced protection features. Best for: BLDC motor control, pump drives, fan controllers, and actuator control. Both series are AEC-Q100 qualified and share development tools for easy migration.

Use ASM87 for general body control. Use ASM30 for motor control applications requiring advanced drive capabilities.

Selecting SineMicro power management ICs involves several key factors: 1) Input Voltage Range - determine the system voltage (typically 12V or 24V automotive battery) and select LDOs with appropriate input voltage ratings (typically 40V-60V max for automotive). 2) Output Voltage - select fixed or adjustable output voltage based on load requirements (common: 3.3V, 5V). 3) Output Current - calculate maximum load current including margins (typically 100mA-500mA for MCU power). 4) Quiescent Current - important for standby power consumption, look for low IQ options (<100uA) for always-on applications. 5) Protection Features - ensure over-current, over-temperature, and reverse polarity protection for automotive reliability. 6) Package - select appropriate package for thermal dissipation and PCB space (SOT-223, TO-252, etc.). SineMicro offers automotive-grade LDOs with various current ratings and features to match your specific requirements.

Define voltage, current, and protection requirements first. SineMicro LDOs offer automotive-grade reliability with competitive performance.

Key parameters for SineMicro MOSFET selection: 1) Voltage Rating (VDS) - must exceed maximum system voltage with margin (typically 40V-100V for 12V automotive systems). 2) Current Rating (ID) - must handle maximum load current with thermal considerations (check SOA curves). 3) On-Resistance (RDS(on)) - lower is better for reduced conduction losses and heating. 4) Gate Threshold (VGS(th)) - ensure compatibility with drive voltage (typically 2.5V-4.5V for logic-level drive). 5) Switching Characteristics - consider switching frequency and requirements for Qg, Ciss for high-frequency applications. 6) Package - select based on thermal requirements and PCB space (SOP-8, DPAK, D2PAK, etc.). 7) Avalanche Rating - important for inductive load switching. SineMicro automotive MOSFETs offer low RDS(on), robust avalanche capability, and AEC-Q101 qualification for reliable automotive operation.

Match voltage and current ratings to application requirements. Consider thermal design for high-current applications.
