If a Hall element requires a lower voltage than the H-Bias output, connect an appropriate value resistor between the H-Bias pin and the Hall element supply pin. NEW PRODUCT H+ and H- – Hall Inputs The rotor position is detected by a Hall sensor, with the output applied to the H+ and H-pins. This sensor can be either a 4 pin 'naked' Hall device or of the 3 pin buffered switching type. For a 4 pin device the differential Hall output signal is connected to the H+ and H- pins. For a buffered Hall sensor the Hall device output is attached to the H+ pin, with a pull-up attached if needed, whilst the H- pin has an external potential divider attached to hold the pin at half Vref. When H+ is high in relation to H-, out2 is the active drive. VREF – Output Reference Voltage This is a 6V nominal reference output voltage. It is designed to 'source' current and therefore it will not 'sink' any current from a higher voltage. The total current drawn from the VREF pin by any external circuitry, such as the minimum speed potential divider to VMIN pin, should not exceed 5mA. COSC Pin A capacitor at the COSC pin generates a triangular waveform which is compared with VPWM (or VMIN) to generate output Pulse Width Modulated (PWM) drive for speed control. A capacitor of 100pf capacitor connected between COSC and ground a 25 kHz triangle wave with high level voltage is 0.3VCC typical and low level voltage of 0.16VCC typical. For 12V supply, the high and low level thresholds are 3.6V and 1.95V. VPWM - Speed control Input The voltage applied to the VPWM pin provides control of the motor speed by varying the PWM drive ratio at the out1 and out2 outputs. The control signal should be a variable DC voltage input of range 3.6V to 1.95V for nominal 12V supply, representing 0% to 100% drive respectively. If variable speed control is not required this pin can be tied to an external potential divider to set a fixed speed or tied to ground to provide full speed i.e. 100% PWM drive. If external input PWM signal is used to control the speed, this input PWM signal needs to be converted to a DC voltage to meet the VPWM pin input range. VMIN – Minimum Speed Setting A voltage can be set on this pin via a potential divider between the VREF (or Supply) and GND pins. This voltage is monitored by the VPWM pin to clamp the VPWM control voltage so that it does not rise above VMIN voltage. As a higher voltage on the VPWM pin represents a lower speed, the VMIN setting prevents the motor speed going lower than the minimum speed set by the VMIN pin. When the VMIN voltage is higher than the lowest speed setting voltage allowed (The lowest speed voltage is about 0.28VCC), the fan speed is maintained at the at the lowest speed. CT Pin – Locked Rotor Timing Capacitor The CT pin will have a capacitor connected to ground. It is a multi-function pin providing timing for the lock detect and auto-restart. Different rates of charge and discharge of CT capacitor depending on the mode of operation (fan operation status) give the lock-detect time (T LCKDET ) and lock time (T OFF ) before next auto-start retry. When the motor is running, the capacitor is discharged at every Hall signal change. CT pin provides the timing for the Locked Rotor monitor. In normal operation, Lock Detect is enabled. If the Hall signal does not change (i.e. a rotor lock condition) within the Lock Detect time (T LCKDET ), the outputs are disabled. In this condition the motor will not be driven for a set time T OFF . This T OFF time depends on the external CT capacitor value and its internal discharge current (I DHG ). After the T OFF period device enter auto-restart phase to re-start the motor with a new Lock Detect time. If the motor has not turned to generate a transition on the Hall inputs by the end this T LCKDET period, motor re-enters motor lock T OFF period with outputs disabled. If the Hall signal change is detected, the motor is deemed as running and goes into lock-detection mode. The T LCKDET and T OFF are determined by the value of the external capacitor on the CT pin and the internal charge and discharge currents during these time periods. The currents during, T LCKDET and T OFF are I CHG , and I DHG respectively. FG – Frequency Generator (Tachometer) Output This is the Frequency Generator output and is a buffered signal from the Hall sensor. This is an open collector drive giving an active pull down with the high level being provided by an external pull up resistor. AM4961A Document number: DS36626 Rev. 1 - 2 6 of 17 www.diodes.com October 2013 © Diodes Incorporated A Product Line of Diodes Incorporated AM4961A Functional Descriptions RD Pin This is the fan locked status detector. This is an open collector drive giving an active pull down with the high level being provided by an external pull up resistor. When fan is locked, RD pin is in off state. Out1 and Out2 pin NEW PRODUCT Out1 and out2 pins provide H-bridge driver output for fan and motor coil connection. V CC – I C Supply Voltage This provides the supply for the device.

C1 is for power stabilization and should be 1uF or higher depending on the motor current and motor design. Power Supply Stabilization The recommended operating voltage range for AM4961A is 3.5V to 16V. A decoupling capacitor C1 (which also acts as re-circulating capacitor at commutation) should be connected close to the V CC pin. C1 is for power stabilization and should be 1µF or higher depending on the motor current and motor design. Hall Bias and Hall Input for Commutation Signal The HB pin provides a 1.25V Hall bias voltage to drive Hall element. The output of the Hall elements or the Hall switches connect to Hall input H+ and H- pin as described previously in functional description section. To avoid noise, the connection to the Hall element or switch should be as short as possible. The Hall input stage (H+ and H- pin) has a hysteresis of 20mV typical. The differential Hall input signal should be 50mV peak or higher. Output PWM Frequency Setting – CSOSC Capacitor The output PWM frequency is generated by comparing VPWM or VMIN (whichever is lower) to the triangular wave on the COSC pin. See “Speed Control and Minimum Speed Setting” figure. The triangular wave is generated at the COSC pin when a capacitor C3 is connected between it and the ground. The triangular wave has high level of 0.3VCC typical and low level voltage of 0.16V CC typical. For 12V nominal supply these two levels are 3.6V and 1.95V typically. The capacitor C3 of 100pF at COSC pin provides output PWM frequency of 25kHZ typical. The C3 capacitor should be connected close to the COSC pin. AM4961A Document number: DS36626 Rev. 1 - 2 9 of 17 www.diodes.com October 2013 © Diodes Incorporated A Product Line of Diodes Incorporated AM4961A Applications Note (cont.) Speed Control M NEW PRODUCT The motor speed is governed by the output PWM duty of the H-Bridge. The voltage on the VPWM, VMIN pin and COSC pin controls the output PWM duty and therefore the speed of the motor. When the VPWM voltage is smaller than VMIN voltage, the output PWM duty is generated by comparing the triangular voltage at COSC pin with VPWM. If the VPWM pin voltage is higher than the VMIN pin, the speed is controlled by comparing COSC voltage with VMIN voltage. When the VPWM voltage is lower than the low side of the COSC voltage, the motor will run at full speed. See “Speed Control and Minimum Speed Setting” figure. An input DC voltage from 3.6V to 1.9V (for 12V supply) on the VPWM pin controls the output PWM duty form 0% to 100% thus allowing speed control from 0% to 100% of the full speed. If variable speed control is not required the pin should be tied to an external voltage through a potential divider for a fixed speed or tied to ground for full speed (i.e. 100% output duty PWM drive). The potential divider for a fixed voltage can be supplied by the supply voltage (as shown in typical application circuit) or by the VREF provided the maximum current drawn out form the VREF pin is below 5mA. For speed control based on ambient temperature, a thermistor can be used as one of the resistors in the potential divider. If an external input PWM signal is used to control the motor speed, the input PWM signal can be converted to a DC level with transistor Q1, resistors R1 to R and an integrating capacitor C2. See typical application circuit.

Minimum Speed Setting NEW PRODUCT The minimum speed setting prevents the motor speed dropping below a set speed when the speed demand is too low (i.e. VPWM voltage is closer to 3.6V) When the VPWM pin voltage higher than the VMIN voltage, VMIN voltage is compared to the COSC pin to generate output PWM duty. Therefore, setting VMIN to certain fixed voltage forces the VMIN to control the speed even when the PWM voltage is higher. The output PWM duty will be clamped to the PWM duty represented by the VMIN voltage when the speed demand is lower than the set minimum. If VMIN is not used or application does not need to set the minimum speed, connect the VMIN to VPWM directly. When the VMIN is connected to the VPWM the minimum output PWM duty defaults to 10%. Rotor Lock Detect and OFF time Setting The capacitor C4 from CT pin to the ground provides the timing for the lock detect and auto-restart. The capacitor C4 is charges and discharged by the CT pin at a fixed rate depending on the mode of operation (fan operation status) and therefore the value of the C4 to gives lock-detect time (T LCKDET ) and lock time (T OFF ) before next auto-start retry. The Am4961A returns the C4 voltage to the low threshold, V CTL (1.77V), each time the Hall sensor provides the commutation signal. C4 is charged with I CHG which is typically 2µA. If the voltage on the C4 reaches the high threshold, V CTH (3.7V) before the next Hall signal change, the output will be shutdown and the device will enter lock condition. TLCKDET = C4 (VCTH − VCTL) ICHG The thresholds voltage and charge current are fixed, therefore the T LCKDET time depends only on the value of C4. For C4 of 0.47µF, T LCKDET is 0.47s TLCKDET = C4 × 1 × 10 6 If lock detection causes device to enter output shutdown, the CT pin will discharge the C4 capacitor with I DHG provide T OFF period. The T OFF is the time the device waits before next auto-restart. During T OFF period, the C4 is discharged for the high threshold, V CTH to low threshold V CTL at the discharge current I DHG which is typically 0.2µA. C4 (VCTH − VCTL) TOFF = IDHG The thresholds voltage and discharge current are fixed, therefore the T OFF time depends only on the value of C4. For CT of 0.4µs, T OFF is 4.7s before the next auto restart. TOFF = C4 × 10 × 10 6 Thermal Shutdown AM4961A includes a thermal shutdown function. When the device junction temperature is higher than 176 ºC typical, the thermal shutdown function is triggered and the low side output transistors in H- bridge driver will be turned off. When the IC junction temperature drops below 148°C typical, the device will recover.
