Applications
VNH2SP30 is widely used in robotics platforms, motorized hobby vehicles, and automotive window/seat actuators where high current DC motor driving is required from a microcontroller PWM signal. Its 30 A current capability supports motors in the 100 W to 300 W range without external power transistors or gate drivers. The integrated fault-protection features simplify compliance in industrial motor control designs where overload and short-circuit protection are mandatory.

Frequently Asked Questions
How much continuous current can VNH2SP30 supply and what motor power range does that support at 12 V?
VNH2SP30 is rated for 30 A continuous output current with peak currents up to 30 A limited by the internal current limiter. At a 12 V motor supply this corresponds to continuous shaft power of approximately 300 W, sufficient for driving medium-sized DC motors used in robotic arms, motorized carts, and high-torque actuators without any external power MOSFET stages.
What built-in protections does VNH2SP30 include and how do they prevent damage in short-circuit conditions?
VNH2SP30 integrates overcurrent protection that clamps output current at the trip threshold, thermal shutdown that disengages the output when the junction temperature exceeds 170 degrees C, and undervoltage lockout that disables switching below safe supply levels. A dedicated diagnostic pin pulls low during fault conditions, allowing the host MCU to detect a fault within microseconds and log or respond before motor or wiring damage occurs.
Can VNH2SP30 be controlled directly by a 3.3 V microcontroller PWM output for speed regulation?
VNH2SP30 input logic is compatible with both 3.3 V and 5 V logic levels, accepting PWM signals for speed control on its INA and INB direction pins and a separate PWM input pin. The device supports PWM frequencies up to 20 kHz, enabling smooth and audibly quiet motor speed control. Direction is set by the logic states of INA and INB, and a single PWM duty cycle from 0% to 100% varies speed from stopped to full speed.
For a robotics application using VNH2SP30, what supply voltage range is supported and how should the thermal design be approached?
VNH2SP30 operates from 5.5 V to 16 V on the motor supply (VS) with transient tolerance up to 41 V, making it compatible with 6 V, 7.2 V, 12 V, and 14.4 V battery packs commonly used in robotics. The MultiPowerSO-30 package has an exposed thermal pad that should be soldered to a copper area of at least 1 cm squared or connected to a heatsink to dissipate the 2 W or more of power at full load, keeping the junction below the 150 degrees C continuous rating.
