30 Amp H-Bridge driver

30 Amp H-Bridge is an H-Bridge driver based VNH3SP30 designed to generate two-way drive with up to 30 A continuous current at a voltage of 5.5 Volts to 36 Volts (IC VNH2SP30 only up to 16V). Equipped with a load current sensor circuit that can be used as feedback to the controller. This module is able to drive inductive loads such as DC motors, stepper motors, relay coil, selenoida, and other expenses.


  • Consists of a full H-Bridge driver. (IC VNH2SP30 features the current sense).
  • Driver was able to spend 30 A continuous current and supports the load voltage from 5.5 V to 36 V (IC VNH2SP30 only up to 16V).
  • Input compatible with TTL and CMOS voltage levels.
  • Output tri-state.
  • Output MOSFET with low drain-source resistance (0.034 ohm typ.).
  • Supports PWM control with a frequency of up to 20 Khz.
  • Fault detection.
  • Short-circuit protection and overtemperature protection.
  • Undervoltage and overvoltage shutdown.
  • Reverse battery protection.
  • Input power supply lines (logic) is separate from the power supply to the load path.
  • PCB design with industry standard 2 layer FR4 material and the plated through hole (PTH).
  • Dimensions: 7.4 cm (p) x 6.1 cm (l) x 1.9 cm
