DESCRIPTION
Honeywell’s Anisotropic Magnetoresistive (AMR) 2-Pin
Pulse Width Modulated (PWM) Speed and Direction Sensor
Integrated Circuit (IC) is designed to detect the speed and
direction of a ring magnet encoder target using a unique*
bridge design. The frequency of the digital supply current is
proportional to the rotational speed of the target, and the
rotational direction is encoded by modulating the pulse width
of the supply current. The sensor IC works over a wide range
of speeds, temperatures and air gaps.
• AECQ100-H qualified
DIFFERENTIATION
Honeywell’s unique solution utilizes the AMR bridge in
saturation, which provides a more stable output response
when the system has vibration, sudden air gap changes,
or target runout without requiring complex magnitude
compensation algorithms. The AMR signal has greater
sensitivity than Hall-effect sensor ICs, and does not require
automatic gain control or chopper stabilization that can lead
to increased jitter over the operating range.
POTENTIAL TRANSPORTATION APPLICATIONS
• Transmission speed and direction sensing
• Direction for Anti-lock Brake Systems (ABS) and auto parking
(For ISO26262 Function Safety applications a Safety Manual
is available upon request.)
PORTFOLIO
The Honeywell VM721D1 2-Pin PWM Speed and Direction
Sensor IC joins the following related products:
• VM721V1 AMR 2-Pin Speed Sensor IC
• VM821Q1 AMR 4-Pin Quadrature Sensor IC
VALUE TO CUSTOMERS
The VM721D1 sensor IC has a higher sensitivity AMR bridge
array that operates with a larger airgap than Hall-effect
sensor ICs, which allows for enhanced design flexibility and
assembly tolerances. The sensor IC has been optimized to
provide an output that is not affected by target runout or
sudden air gap changes. It is insensitive to magnet pole size,
allowing one sensor to be paired with different ring magnets.
The VM721D1 sensor IC contains an integral capacitor
for EMC protection, eliminating the need for an external
capacitor in most applications. The wide leads are designed
for a welded assembly, making the part easier to mount in
customer applications.
