SG Micro 8‑Channel Low‑Side Driver SGM42408Q for 12V & 24V Automotive Applications
SG Micro’s SGM42408Q is an 8‑channel low‑side driver compatible with both 12V and 24V automotive systems, supporting direct GPIO drive or 16‑bit SPI control. With a low on‑resistance of 570 mΩ, each channel can deliver up to 1.2 A peak current.
The device is AEC‑Q100 Grade 1 certified, operates over a ‑40°C to +125°C temperature range, and withstands output‑port voltages up to 56 V. Its near‑zero static current in shutdown mode combines low power consumption with high reliability.
Integrated fault‑diagnostic features include open‑load detection, short‑circuit protection, over‑current protection, and over‑temperature protection. Fast turn‑on/off and built‑in clamp protection make it suitable for resistive and inductive loads as well as industrial PLC I/O modules, offering a reliable multi‑channel drive solution for automotive and industrial control.
3PEAK High‑Side Switch TPW20400QQ for Automotive Cameras
3PEAK’s next‑generation low‑power four‑channel high‑side switch TPW20400QQ targets automotive cabin and ADAS applications, specifically designed for in‑vehicle cameras and radar.
AEC‑Q100 certified, the chip provides key protection functions such as over‑current, short‑circuit, open‑load detection, thermal shutdown, and configurable output current limiting. It uses an I²C interface for configuration and status readback, supports four independent channels that can be individually switched and current‑limited, and precisely matches the power‑management needs of multi‑camera systems in ADAS and smart cabins.
Key advantages include low standby power across the full temperature range, a wide 3 V–12 V input voltage range, a compact 4 mm × 4 mm package that saves space, and support for multi‑channel parallel operation to meet higher‑current loads, simplifying the design of automotive power‑protection systems.
Geehy Automotive High‑Side LED Driver GALT62120
Geehy’s GALT62120 automotive high‑side LED driver delivers 12‑channel precision high‑side current outputs, enabling pixel‑level independent LED control. It integrates a programmable 12‑bit PWM dimming function that supports both linear and exponential dimming modes.
AEC‑Q100 Grade 1 certified, the device includes LED open‑/short‑circuit detection and over‑temperature protection, making it suitable for a wide range of automotive lighting applications such as through‑type/graphical tail lights, headlamps, dynamic sequential lights, welcome lights, instrument‑cluster lighting, and interior ambient lighting.
Silan High‑Precision Automotive LED Driver IC SQ9000
Silan’s SQ9000 is an automotive‑grade LED driver controller developed on the company’s own DTI process platform, ensuring a fully domestic, self‑controlled solution. It is fully compliant with AEC‑Q100 Grade 1 and targets automotive LED headlamps, emergency lighting, and general LED lighting.
The product features an extremely wide input voltage range of 4.5 V to 65 V, compatible with 12 V and 24 V battery systems. Using a high‑accuracy peak‑current control mode, it supports topologies such as BUCK and BUCK‑BOOST and achieves ±4% LED constant‑current accuracy across the operating temperature range.
It supports both analog and PWM dimming, integrates a P‑channel MOSFET driver for fast response, and includes comprehensive protection functions with status feedback. Packaged in an HTSSOP‑20 with bottom‑side thermal pad, it balances thermal performance with eco‑friendly design. Leveraging mature processes, Silan’s automotive‑grade products have already entered volume supply to leading automakers, with performance comparable to mainstream international solutions.
NOVOSENSE ASIL‑C‑Ready E‑Drive Solution Based on QM‑Grade Isolated Drivers
As safety requirements for new‑energy vehicles rise, e‑drive systems have become key units for vehicle‑torque safety control. In line with the forthcoming mandatory national standard GB 21670 (effective 2026), NOVOSENSE has introduced an ASIL C functional‑safety solution based on its QM‑grade isolated driver series NSI67xx‑Q1.
The solution has been evaluated and certified by DEKRA. The core NSI67xx‑Q1 series offers distinct advantages: integrated isolated analog sampling simplifies design; CMTI ≥ 150 kV/μs provides high noise immunity; ±10 A source/sink current meets high‑power‑density needs of SiC/IGBT; robust design, comprehensive safety‑protection mechanisms, and flexible packaging options are complemented by solid production‑validation records. This enables customers to implement low‑change, cost‑effective, and fast‑to‑market e‑drive system solutions.
ICgoodFind : The launch of these multiple automotive‑grade chips and solutions demonstrates the technical strength of domestic suppliers. Covering core automotive scenarios with high reliability and adaptability, they will further accelerate the localization upgrade of automotive electronics.
