Mingjiada Electronics: Supply Original [ON] NCV7720DQAR2G Deca Ten-Channel Half-Bridge Driver
Product Details
The NCV7720DQAR2G is a monolithic integrated high-side and low-side driver capable of independently controlling up to 10 half-bridge output channels. Each channel contains a high-side (HS) and a low-side (LS) MOSFET driver that can directly drive external N-channel power MOSFETs to build a complete half-bridge topology. This design provides great flexibility for driving bi-directional DC motors, stepper motor windings, solenoids, or high-current LED clusters.
Designed for space-saving applications, the NCV7720DQAR2G is available in a compact 48-pin HTSSOP package (suffix DQAR2G). Compliance with the stringent automotive electronics AEC-Q100 standard (Class 1) ensures reliable operation in harsh automotive environments such as engine compartments, with an operating temperature range of -40°C to +125°C.

KEY FEATURES
High Integration (10 Channels): The NCV7720DQAR2G integrates 10 independent half-bridge drivers on a single chip, dramatically reducing component count, PCB area, and system complexity, making it especially suitable for applications where multiple actuators need to be driven (e.g., automotive seat modules, door modules).
Powerful SPI Control and Diagnostics: Through the standard SPI interface, the microcontroller can easily configure the operating mode of each channel (high side open, low side open, half-bridge, high-resistance state), read detailed diagnostic information (over-current, over-temperature, open load, under-voltage, etc.), to achieve precise control and powerful system status monitoring, to enhance the safety and maintainability of the system.
Comprehensive Protection Functions: The device has built-in multi-layer protection mechanisms, which are the core of its high reliability:
Overcurrent Protection (OCP): detects and limits the output current of each channel to prevent MOSFETs from being damaged due to short-circuit or overload.
Temperature Shutdown (TSD): Automatically shuts down all output channels when the chip temperature exceeds the safety threshold, and restores them automatically when the temperature drops.
Under Voltage Lockout (UVLO): Disables the outputs when the supply voltage is too low, ensuring that the MOSFETs operate in a safe switching region.
Open Load Detection (OLD): Detects if the load is disconnected (open) when the output is turned off, helping to identify loose connectors or harness faults.
Short Circuit Protection (SCP): Effectively responds to output short circuits to ground or to power.
Automotive Grade Reliability: Meets AEC-Q100 Grade 1 standards and is designed to meet the stringent temperature, vibration and electrical environmental requirements of automotive electronics.
High-side drive capability: Integrated bootstrap diodes simplify the design of bootstrap circuits required to drive high-side MOSFETs.
Application Information
With its high channel count, integration, reliability, and powerful diagnostic capabilities, the NCV7720DQAR2G is targeted at automotive electronics and industrial applications that require centralized control of multiple loads:
Automotive Body Control Modules (BCMs): drive window lifters, door lock actuators, mirror adjustment motors, seat adjustment motors, and LED lighting (daytime running lights, taillights, interior lights).
Automotive HVAC system: drive the air-conditioning system in the valve actuator, blower speed module (with MOSFET).
Automotive powertrain: drive small solenoid valves (such as turbo control valves), cooling fans.
Industrial automation: control of factory automation equipment in the multiple solenoid valves, small DC motors, stepper motor windings, PLC output modules.
High-end lighting control: drive high-current, multi-channel LED string or matrix.
