AP1025BEN
45V Single Stepper Motor Driver IC
1. Description
The AP1025BEN provides a complete stepper motor driver solution with built-in LDMOS FET and its
internal capacitors type charge pump circuit for the 45V & 1.6A constant current operation. Clock-in input
mode and Parallel input mode is selectable by the setting of an external terminal. 2 phase, 1-2 phase(1/2step),
W1-2 phase(1/4step) can be selected during parallel input mode, and 2 phase, 1-2 phase(1/2step), W1-2
phase(1/4step), 4W1-2 phase(1/16step) can be selected during clock-in input mode to realize calm motor
operation. The IC is housed in a small 32-pin QFN package and excellent in heat dissipation. It also includes
under voltage detection and thermal shut down circuits. It is suitable for various types of stepper motors.

10.4 PWM Current Control
The current value of 100% PWM constant current setting ratio at each excitation mode of AP1025 (Iload
(100%) [A]) is determined by H-Bridge sense resistor(RIS) and PWM constant current setting voltage(VIS) as
follows.
Iload (100%)[A] = (VIS / 2.5) / RIS
PWM constant current setting voltage

RIS
Calculation example1:VIS=1V, RIS=0.5ohm
Iload (100%)[A] = (1 / 2.5) / 0.5ohm = 0.8A
--- (2)
The minimum value of the control current in the PWM constant current control in each excitation mode (Iload
(min) [A]) is determined by the following equation.
Iload(min)[A]=VM/(Rm+RON+RIS) × tB × fCP

Calculation example2:VM=24V, fCP=25kHz, tB=2.23us, Rm=9.4ohm, RON=1ohm, RIS=1ohm
Iload(min)[A]=24V/(9.4ohm+1ohm+1ohm) × 2.23us × 25kHz = 0.117A
--- (4)
The current value of 100% PWM constant current setting ratio should be set so that the minimum control
current (Iload (min) [A]) becomes larger than the minimum value of the PWM constant current setting ratio in
4W1-2 phase excitation. In case of calculation example 2, the current value of the 100% PWM constant
current setting ratio (Iload (100%) [A]) is as follows.
Iload(100%)[A]=0.117/9.8%=1.19A
---(5)
If the current value of 100% PWM constant current setting value ratio (Iload (100%) [A]) is smaller than
equation (5), minimum control current value (Iload (min) [A]) may be larger than 9.8%.

10.5 Decay Mode
The AP1025 selects decay mode automatically for better current following property. Basically, it operates in
slow decay mode, but it operates in fast decay mode when the current setting value is lowered, till it reaches to
the setting value.

10.6 Protection Circuits
 Under Voltage Lockout Circuit (UVLO)
UVLO monitors Control power supply voltage (VC) and changes H-bridge driver output to Hi-Z if VC is
lower than the specified value (VVCUV =2.2V) when starting the VC source.
 Thermal Shut Down Circuit(TSD)
As soon as abnormal high temperature (TTSD=150C) is detected, H-Bridge driver output becomes
Hi-Z.

・Shorted-Load, Shorted-to-Ground and Shorted-to-Power Protection
If the motor leads are shorted together, or if one of the leads is shorted to ground or shorted to power, when
current flowing is 3.3A or less, the motor driver IC will protect itself by hiccup behavior of thermal shutdown
circuit (TSD). When there is a power supply capacity of 3.3A or more, the appropriate protection fuse is
implemented between the motor power supply line(VM) and the power supply on the PCB.

Note 16. Above capacitances are examples. Please choose the best external capacitors for CVM, CVC and
CVIS for your system board.
Note 17. Capacitance of CVM and CVC should be adjusted considering the load current profile, the load
capacitance, the line resistance and etc. of the actual system board.
Note 18. Please choose the best external capacitor for CSL as sub harmonic noise measures. If not using the
CSL capacitor, please connect the SL terminal to ground.

Note 19. Please design the ground plane of the PCB as large as possible.
Note 20. Exposed Pad (exposed backside pad) must be connected to the ground of the PCB, because the
ground of IC and Exposed pad is in common.
Note 21. The ground via on the IC mounted area is effective for heat radiation to each layer of the PCB.
