Description : 2.4A/4.4A injector solenoid driver

Description
The CS452/453 is a monolithic integrated circuit designed for medium current solenoid driver applications. Its typical function is to supply full battery voltage to fuel injector(s) for rapid current rise, in order to produce positive injector opening.
When load current reaches a preset level (2.4A for CS452, or 4.4A for CS453), the injector driver reduces the load current by a 4:1 ratio and operates as a constant current source. This condition holds the injector open and reduces system power dissipation.
Other solenoid or relay applications can be equally well served by the CS452/453. Two high impedance inputs are provided which permit a variety of control options and can be driven by TTL or CMOS logic.

Part Name(s) : STK673-010

Description : 3-Phase Stepping Motor driver (sine wave drive) Output Current 2.4A

Overview
STK673-010 is a 3-phase stepping motor driver hybrid IC with built-in microstep controller having a bipolar constant current PWM system, in which a power MOSFET is employed at an output stage.
It includes a 3-phase distributed controller for a 3-phase stepping motor to realize a simple configuration of the motor driver circuit.

Features
• Number of motor revolution can be controlled by the frequency of external clock input.
• 4 types of modes, i.e., 2, 2-3, W2-3 and 2W2-3-phase excitations, are available which can be selected based on rising of clock signals, by switching Highs and Lows of Mode A and Mode B terminals.
• Setting a Mode C terminal Low allows an excitation mode that is based on rising and falling of a clock signal. By setting the Mode C terminal Low, phases that are set only by Mode A and Mode B can be changed to other phases as follows without changing the number of motor revolution: 2-phase may be switched to 2-3-phase; 2-3-phase may be switched to W2-3-phase; and W2-3-phase may be switched to 2W2-3-phase.
• Phase is maintained even when the excitation mode is changed
• An MOI output terminal which outputs 1 pulse per 1 cycle of phase current.
• A CW/CCW terminal which switches the rotational direction.
• A Hold terminal which temporarily holds the motor in a state where the phase current is conducted.
• An Enable terminal which can forcibly turns OFF a MOSFET of a 6 output driving element in normal operation
• Schmitt inputs with built-in pull-up resistor (20 kΩ typ)
• Motor current can be set by changing the voltage of the Vref terminal (0.63V per 1A, dealing as much as 0 to 1/2VCC2 (4A)).
• The clock input for controlling the number of motor revolution lies in a range of 0 to 50kHz.
• Supply voltage: VCC1 = 16 to 30V, VCC2 = 5.0V±5%
• A built-in current detection resistor (0.227Ω)
• A motor current during revolution can deal with as high as 2.4A at Tc = 105°C and as high as 4A at Tc = 50°C or lower.

Applications
• As a 3-phase stepping motor driver for transmission and reception in a facsimile.
• As a 3-phase stepping motor driver for feeding paper feed or for an optical system in a copying machine.
• Industrial machines or products employing 3-phase stepping motor driving.

It includes a 3-phase distributed controller for a 3-phase stepping motor to realize a simple configuration of the motor driver circuit.
The number of motor revolution can be controlled by the frequency of external clock input. 2, 2-3, W2-3 and 2W2-3-phase excitation modes are available. The basic step angle of the stepping motor can be separated as much as one-eighth 2-3-phase to 2W2-3-phase excitation mode control quasi-sine wave current, thereby realizing low vibration and low noise.
