AH5773
SINGLE PHASE MOTOR DRIVER WITH
INTERNAL HALL EFFECT LATCH SENSOR
Description
Pin Assignments
NEW PRODUCT
The AH5773 is a high performance, single chip solution for driving
single-coil brushless direct current (BLDC) fans and motors. The
integrated full-bridge driver output stage uses soft switching to
minimize audible switching noise and electromagnetic interference
(EMI) providing a low noise solution.
(Top View)
To simplify circuit design and minimize external components, the
device integrates a stable high sensitivity Hall-effect sensor, voltage
and temperature compensated internal references, amplifiers and the
output H-bridge power switches with low RDSON. For system flexibility,
the motor speed can be controlled by changing the duty ratio of the
PWM signal at the PWM pin or adjusting the supply voltage.

To help protect the motor coil, the AH5773 provides Rotor Lock
Protection which shuts down the output drive if rotor lock is detected.
The device automatically re-starts 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. The device enters standby mode when PWM pin is pulled low
for longer than 65ms. In standby mode, AH5773 consumes less than
100µA.

speed. The FG output is the magnetic change frequency.

Notes:
4. C1 is for power stabilization and to strengthen the noise immunity; the recommended value is 2.2µF. 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 2.2µF, for lower motor current 1µF and higher should be used. If PWM speed control function is not used (PWM pin tied high or not
connected) the capacitor value can be reduced towards 0.1µF. The value of the C1 should be checked in the motor design in its operating conditions if it
is reduced from the recommended value of 2.2µF.
5. The AH5773 has an open-drain tachometer FG output that follows the magnetic change frequency. Typically a pull-up resistor of 10kΩ is recommended
from FG pin to the supply voltage.

in production. They are guaranteed by design, characterization and process control.
14. DPWM_MIN is the device output PWM duty-range capability. The minimum PWM duty ratios need to start the motor turning or maintain the rotation of the

Notes:
18. In “Normal Spinning”, the FG changes its state at each edge of O1.
19. When the motor locks with South pole at the Hall element, O2 is kept on “L” and O1 is a clock with tON/tOFF ratio.
When motor locks with North pole at the Hall element, O1 is kept on “L”, O2 is a clock with tON/tOFF ratio.
20. When “Re-start spinning” occurs, the motor speed ramps up to the “Normal Spinning” speed from zero.
Speed ramp-up profile depends on motor characteristics.
21. In standby mode FG switch is turned off to save system power.

Application Note
DC Supply Voltage Speed Control
Motor speed can be controlled by varying the VDD supply voltage while PWM pin is tied to VDD pin.
For example, with 12V nominal motor, changing supply voltage between 12V to 2.4V, speed can be reduced from 100% to 20% typically.
NEW PRODUCT
PWM Speed Control
Motor speed can also be adjusted by applying a PWM speed control signal into the PWM pin while keeping the VDD pin at nominal motor voltage.
The motor speed is proportional to the PWM signal duty. For example, with 12V nominal motor, VDD pin is maintained at 12V typical while
varying the PWM control signal duty to adjust the motor speed linearly. The figure below shows the output O1 and O2 in relation to PWM speed
control signal at PWM pin.

Frequency of PWM speed-control signal can be between 50Hz to 50kHz. Recommended typical PWM signal frequency is 25kHz to keep
switching frequency away from audible band. AH5773 has a very good input to output PWM linearity over the operating range for no load
conditions (i.e. no motor coils connected to the output). When the motor coil is connected, the nonlinearity of coils and permanent magnet profile
will introduce non-linearity to the motor speed against input PWM duty ratio.

If PWM signal level at PWM pin stays low for longer than 65ms typical, the outputs are disabled.
Depending on the motor design and its inertia, at nominal voltage (i.e. 12V for 12V motor), minimum start-up PWM duty required can be typically
between 20% - 45% while minimum running PWM duty can be down to 10% - 25% typical. If voltage at VDD is lower than the nominal motor
voltage, both start-up PWM duty and minimum running PWM duty required will be higher.

Application Note (continued)
Standby Mode and Quick Start
When PWM signal input at PWM pin is low for longer than 65ms, internal rotor lock protection tOFF is cleared and the device enters standby mode.
In standby mode typical supply current is less than 100µA. This allows the device to enter motor start tON time on the next PWM high signal
providing a quick start. When the device is enabled again, the Hall sensors take 100µs to stabilize.
