DIRECT PWM MOTOR DRIVER
Description
Pin Assignments
The AM9469 is a high performance, ultra-low noise single phase
(single-coil) brushless direct current (BLDC) fan and motor driver. The
integrated full-bridge driver output stage uses BTL linear driver
architecture to minimize audible switching noise and Electromagnetic
Interference (EMI) providing a low noise solution.

For system flexibility the motor speed can be controlled by either an
external PWM signal or by a DC voltage or from a thermistor network.
Based on the input signal, the AM9469 adjusts the output duty cycle.
To help protect the motor coil, the AM9469 provides Rotor Lock
Protection which shuts down the output drive if rotor lock is detected.
The device automatically restarts when the rotor lock is removed. In
case of over voltage, the device shuts down the output drive and
enters standby mode to help prevent over voltage stress on the coil.
Over temperature shutdown provides thermal protection for the
device.
A Tachometer output is provided by the open-drain Frequency
Generator (FG) Pin which allows external interface to monitor motor
rotation or speed. The FG output is the magnetic change frequency.
Additionally, a rotor lock detect output is provided by the open-drain
RD Pin.

AM9469 is available in thermally enhanced TSSOP-16EP with
exposed pad.

Notes:
4. C1 is for power stabilization and to strengthen the noise immunity and should be as close to the VDD pin as possible. The recommended value for C1 is
1µF typically. The value of capacitor can be optimized depending on the operating mode, motor voltage and the motor current. For PWM speed control
mode, with datasheet current capability, the recommended capacitor value is 1µF. The value of the C1 should be checked in the motor design and route
in its operating conditions if it is reduced or increased from the recommended value of 1µF.
5. Diode D1 is for the reverse connection protection. In addition to power stabilization and noise immunity, C1 also absorbs regenerative motor spikes.
Depending on the amount of regenerative voltage spike, value of C1 needs to be adjusted. The zener diode Dz is used to clamp the regenerative
voltage spike form the motor operation to safe level when reverse blocking diode D1 is used. If reverse blocking diodes is not used, the use of zener
clamp Dz depends on the supply voltage capability to effectively sink the regenerative energy and voltage spike. The value of C1 and the requirement
Dz needs to be verified on each application design.

Operating Characteristics
Standby and Start-Up Timing
When the PWM Pin input signal is logic “L” level continuously for a longer time than tSLP, the device enters standby mode as shown below. When
the PWM Pin signal is “H” level, the device turns active and operates normally. The PWM Pin is also used to control the motor speed with external
PWM signal into this pin. The lowest frequency PWM signal is defined by tSLP, i.e. the PWM duty low time has to be smaller tSLP for motor speed
control.

Application Notes
H-Bias – Hall Bias Output
This is a 1.25V nominal voltage source to bias a differential un-buffered Hall element sensor. 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.
H+ and H- – Hall Inputs
The rotor position is detected by a Hall sensor, with the output of Hall sensor 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 HPins. For a buffered Hall sensor, the Hall device output is attached to the H+ Pin, with a pull-up attached if needed. Meanwhile, 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.
PWM Pin – External PWM Signal Input for PWM Speed Control Mode
In PWM speed control mode, external PWM signal is applied at this PWM Pin to control the motors speed. The duty ratio of the PWM signal input
to this pin controls the fan motor speed by varying the output PWM drive directly.
CPWM Pin
Internal motor control triangular wave is generated based on the capacitor on this pin. A capacitor of 100pF (CPWM = 100pF), will provide a
triangular wave of 36kHz (typ). The VCONT and RMI signals are compared with this triangular wave to generate the speed control PWM drive and
minimum speed control clamp points. The output PWM drive frequency is the same as the triangular waveform frequency.
FG/RD Pin
FG is the Frequency Generator (tachometer) output and is a buffered signal from the Hall sensor. RD is the fan locked status detector. GF and
RD are open-drain outputs and will require external pull-up resistors. Typically, a pull-up resistor of 10kΩ is recommended from the FG and RD
Pins to the supply voltage.
RF Pin
The current limiter is activated when the voltage between current detection resistor exceeds 0.25V between GND and RF. The current limiter is
activated at IO = 250mA when RF = 1Ω. The current limit is set with a RF resistor between the RF Pin and GND Pin.
RMI Pin – Minimum Speed Setting Pin
RMI is the minimum speed setting pin. DC voltage on this pin sets the minimum speed value. If you do not use RMI (minimum speed control),
please connect it to 5VREG.
VCONT Pin – DC Voltage Speed Control
VCONT is DC voltage inputs speed control pin. The voltage on the VCONT Pin is compared with the triangular oscillation on the CPWM Pin to
generate the output drive PWM signal. For the control method, refer to the timing chart.
REGH/5VREG Pin
Please insert capacitor value 1µF between 5VREG and GND for regulated output voltage stabilization; insert capacitor value 1µF value between
VDD and REGH for stable output voltage.
OUT1 and OUT2 Pins
OUT1 and OUT2 Pins provide H-bridge driver output for fan and motor coil connection.
VDD – Device Supply Voltage
This provides the supply for the device.
GND – Supply Return
This is the device supply ground return pin for control signal.

Application Notes (Continued)
Speed Control
This device allows both the DC voltage input and PWM signal input for speed control. Typically, only one of the methods is used to control the
motor speed. In DC voltage speed control mode, the voltage on the VCONT Pin is compared with the CPWM triangular wave to generate
internal PWM signal to drive the output. In PWM speed control mode, the PWM signal on the PWM Pin directly controls the output PWM drive.
The typical application circuits shows the two speed control methods.
