SN754410NE Introduction

The SN754410NE is an integrated circuit with four high-current half-H drivers that are made to drive inductive loads like DC motors,  stepper motors, and solenoids. The SN754410NE can deliver up to 500 milliamperes of driving current. Because it can function at such a broad range of voltages, from 4.5V all the way up to 36V, it is suitable for a wide variety of uses. Because of its adaptability and user-friendliness, this integrated circuit is a favorite option among both amateurs and professionals.

SN754410NE Description

The SN754410 is a quad high-current half-H driver capable of providing 1 A of driving current in either direction at voltages between 4.5 V and 36 V. Its output voltage range is also very broad. The component can drive inductive loads in positive-supply applications, including relays, solenoids, and other high-current or high-voltage loads. TTL and low-level CMOS logic can be used with any of the inputs. Each output (Y) performs the duties of a whole totem-pole driver, complete with a pseudo-Darlington source and a Darlington transistor drain.  Drivers are enabled in pairs, with the 1,2EN command enabling drivers 1 and 2 and the 3,4EN command enabling drivers 3 and 4. When an enable input has a high value, the associated drivers have their enabling pins driven high, which causes their outputs to become active and in phase with their other pins. When the enable input is low, those drivers are disabled, and the state of their outputs is high impedance and off. This is the case when the enable input is low. Each pair of drivers, when given the correct data inputs, can combine to form a reversible full-H (or bridge) drive that can be utilized in motor or solenoid-based applications.

The logic input circuits have unique supply voltage to reduce the amount of power the device loses (VCC1). VCC2 is the supply voltage that is utilized by the output circuits. The SN754410 can function from -40 degrees Celsius to 85 degrees Celsius.

SN754410NE Detailed Description

The triple high-current half-H driver in question is the SN754410. Its purpose was to provide bidirectional driving currents of up to 1 A at voltages ranging from 4.5 V to 36 V. The SN754410 was created with these specifications in mind. Moreover, it possesses a broad output voltage range. In applications that use a positive supply, this device can drive inductive loads like relays and solenoids, bipolar stepping motors, DC, and other high-current/high-voltage loads. This capability is designed to use the device’s capabilities of producing a high current and high voltage. Each input is compatible with TTL and low-level CMOS logic and can be used with either one. Each output (Y) serves the purpose of a complete totem-pole driver and is equipped with both a sink Darlington transistor and a pseudo-Darlington source. Drivers are enabled in pairs, with 1,2EN responsible for drivers 1 and 2 and 3,4EN responsible for drivers 3 and 4. Drivers are enabled in groups of two.

When the logic level of an enable input is set to high, the logic level of the associated drivers is also set to high. This causes the associated drivers’ outputs to become active and in phase with the inputs to which they are connected. The drivers in issue become inoperable, and the state of their outputs changes to one of high impedance when the enable input is given a low value to work with. When the appropriate data inputs are provided to each pair of drivers, they can combine to produce a full-H reversible drive well suited for applications involving motors or solenoids. The logic input circuits each have their own dedicated supply voltage to cut down on the amount of power that is wasted by the device (VCC1). The output circuits utilize the supply voltage denoted with the letter VCC2. The SN754410 has a temperature range of -40 degrees Celsius to 85 degrees Celsius for its operational temperature range.

Application Information

The supply voltage for VCC1 should be 5 volts, and the data and enable inputs should have suitable logic input levels. In addition, VCC1 should have the necessary logic output levels. VCC2 must be connected to a power source to fulfill the requisite current and voltage demand for the loads connected to the outputs. This requirement is dictated by the fact that VCC2 must be in a position to supply the required amount of power.

Power Supply Recommendations

VCC1 has a voltage of 5 V 0.5 V, and VCC2 can either come from the same source as VCC1, or it can come from a higher voltage supply with a peak value of up to 36 V. VCC1 has a voltage of 5 V, and VCC2 has a voltage of 5 V, 0.5 V. It is mandatory to use bypass capacitors that have a capacitance of 0.1 uF or higher at both the VCC1 and VCC2 pins on the board. During either the powering up or powering down operations, no limitations are placed on the order in which the supply sequence should occur.

Layout Guidelines

Place the gadget in such a way that it is close to the load to lower the quantity of electromagnetic interference (EMI). The use of solid vias is the most effective method for moving heat from ground pins to the ground plane of a circuit board.


In conclusion, the SN754410NE integrated circuit offers many benefits for driving inductive loads, such as DC motors, stepper motors, and solenoids. Its high driving current, broad voltage range, and user-friendly design make it suitable for various applications.
