Shenzhen Mingjiada Electronics Co., Ltd., as a professional distributor of electronic components, consistently supplies the ST VND7E050AJTR dual-channel high-side driver, providing robust technical support and supply assurance for automotive applications.
【Core Features of the VND7E050AJTR】
The VND7E050AJTR is a dual-channel high-side driver specifically designed to drive 12V automotive ground loads via 3V and 5V CMOS-compatible interfaces.
Employing advanced VIPower M0-7 technology, the VND7E050AJTR operates stably across a wide 4V to 28V supply range and withstands transient voltages up to 40V.
Each channel features a typical on-resistance of just 50mΩ and delivers up to 9A maximum output current, enabling simultaneous driving of two loads.
Compliant with AEC-Q100 standards, the VND7E050AJTR meets stringent automotive component requirements. Its operating temperature range spans -40°C to +150°C, accommodating extreme thermal conditions within automotive environments.
Its PowerSSO-16 package is optimised for high-power applications, delivering superior thermal performance and compact mounting dimensions.
【Key Parameters of VND7E050AJTR】
Operating voltage range: 4V to 28V, accommodating fluctuations in automotive power systems
On-resistance: Typical value of 50mΩ, effectively reducing power dissipation
Output current capability: Up to 9A per channel, meeting most automotive load driving requirements
Operating temperature range: -40°C to +150°C, compliant with automotive-grade component environmental specifications
【VND7E050AJTR Comprehensive Protection and Diagnostic Capabilities】
The VND7E050AJTR incorporates a high-precision proportional current mirror, providing accurate real-time load current feedback via analogue signal.
This advanced current sensing enables continuous load status monitoring, delivering critical data for fault diagnosis and system optimisation.
Regarding protection features, the VND7E050AJTR offers comprehensive fault protection mechanisms including fixed current limiting, open-load detection, over-temperature protection, over-voltage protection, and short-circuit protection.
When output current exceeds limits, the VND7E050AJTR automatically enters power-limiting mode to effectively manage overloads and prevent damage.
A unique configurable latch function allows users to select either automatic recovery or latch-off mode during over-temperature or power-limit events.
A dedicated fault reset pin (FaultR) enables output unlocking or latch deactivation under fault conditions.
The VND7E050AJTR also incorporates a diagnostic enable/disable feature, permitting deactivation of OFF-state diagnostics during the module's low-power mode to reduce system power consumption.
【VND7E050AJTR Automotive Applications】
The VND7E050AJTR offers extensive application prospects in automotive electronics due to its robust drive capability and comprehensive diagnostic protection features.
Within Advanced Driver Assistance Systems (ADAS), the VND7E050AJTR provides protected power supply for radar, lidar, and various sensors, ensuring reliable operation of safety-critical systems.
Automotive lighting systems similarly benefit from the VND7E050AJTR driver, enabling precise control and comprehensive diagnostics for both traditional halogen headlamps and advanced LED lighting systems.
The VND7E050AJTR can also drive diverse automotive resistive, inductive, and capacitive loads such as valves, actuators, and heaters.
Its ultra-low voltage operation complies with the LV124 standard, enabling it to withstand extreme voltage conditions during automotive cold starts.
