<\/div>\n

Gate drivers<\/a> are essential circuits positioned between the controller and power semiconductor devices. By providing high-current drive and voltage amplification, they ensure efficient switching, fast turn-on\/off times, and protection in applications like electric-vehicle inverters and motor controls.<\/p>\n

Many gate drivers include built-in protection features such as undervoltage lockout (UVLO) and short-circuit protection to improve system reliability.<\/p>\n

With 4-V minimum operating voltage, STMicroelectronics\u2019<\/a> new VNQ9050LAJ 4-channel automotive high-side driver can handle disturbances such as extreme cold cranking operation down to 2.7 V. It leads to heightened vehicle reliability and helps ensure a satisfactory user experience.<\/p>\n

Built on ST\u2019s VIPower M0-9 technology, this device supports diverse load types, enables predictive maintenance, and maintains stable operation even at extremely low voltages. With pin-to-pin compatibility for seamless upgrades, they enhance safety, efficiency, and overall vehicle reliability.<\/p>\n

Quad-Channel High-Side Driver<\/h2>\n

The VNQ9050LAJ is designed to drive 12-V automotive grounded loads through a 3- and 5-V CMOS-compatible interface, providing protection and diagnostics. The device integrates protective functions such as load current limitation, overload active management by power limitation, and overtemperature shutdown with configurable latch-off. <\/p>\n

The part meets the latest version of LV 124<\/a>, the car industry\u2019s stringent quality and reliability test standard for electrical and electronic components. The standard consists of two parts: electrical requirements and tests, and environmental requirements and tests.<\/p>\n

Typical on-resistance is as low as 50 \u2126 to help boost efficiency and save energy.<\/p>\n

Current Mirror<\/h2>\n

The VNQ9050LAJ brings features to protect resistive, capacitive, and inductive loads. These include load-current sensing by implementing an on-chip current-mirror circuit with a sense FET that closely tracks the main power-FET parameters. The current mirror is connected to an external pin that permits connecting a resistor to convert the sensed current into a voltage for continuous load monitoring and detection of abnormal conditions.<\/p>\n

The driver has a sense-enable pin that lets similar devices share the external sense resistor to minimize the BOM. The device also has an overvoltage clamp, thermal-transient limiting, and a configurable latch-off on overtemperature or power limitation with dedicated fault reset pin. Other protective measures include electrostatic discharge protection, loss of ground and loss of VCC<\/sub> protection, and reverse-battery protection.<\/p>\n

In production now, the VNQ9050LAJ<\/a> comes housed in PowerSSO-16 package.<\/p>\n

Isolation Reduces Design Complexity, PCB Footprint<\/h2>\n

Isolated drivers<\/a> are used for high-voltage, high-side applications, providing electrical isolation between the control circuit and the high-voltage side to provide safety for high-voltage systems (e.g., EV chargers and inverters). Using integrated gate-driver ICs significantly reduces design complexity, bill of materials (BOM), and PCB footprint, while increasing overall system reliability. <\/p>\n

To that end, ST also introduced the STGAP2SA<\/a> and STGAP2HSA<\/a> automotive-grade, galvanically isolated 4-A gate drivers with 60-ns response time and close part-to-part matching. Those features lead to high switching frequencies that enhances power density and efficiency. The STGAP2HSA also delivers 6-kV surge isolation.<\/p>\n
