MT1401-EN
Latch, Hall-Effect Magnetic Position Sensor
1 Product Description
The MT1401-EN family is produced by BCD
technology with both high performance and high
reliability. The Hall IC internally includes an on-chip
Hall voltage generator, a voltage regulator for
operation with supply voltage of 2.8V to 24V, a smallsignal amplifier, Hall sensors with dynamic offset
cancellation, a schmitt trigger and an open-drain
output with over-current protection. It features
temperature compensation technique to make the
magnetic switching points stable over a wide
temperature range. Other key features such as reverse
supply voltage protection, output over-current
protection and ESD level exceeding ±6KV (HBM)
make the IC extremely robust and fault tolerant,
which is important in demanding application
environment such as automotive. Its extremely low
operating supply voltage 2.8V also makes it possible
to add external resistance in series with the supply pin
for even greater protection against high voltage
transients from the power supply.
4 Applications
￭ Home appliances，Industrial
￭ DC Fan, Electric tools
￭ Magnetic Encoder
When the magnetic flux density (B) is greater than the
operating point (BOP), the output turns on (Low). The
output is held steady till the magnetic flux density (B)
is less than the releasing point (BRP), at which point it
turns off (High).

7 Function Description
BOP: Operating Point, Magnetic flux density applied on the branded side of the package which turns the
output driver ON (VOUT=Low)
BRP: Releasing Point, Magnetic flux density applied on the branded side of the package which turns the
output driver OFF (VOUT=High)
BHYST: Hysteresis Window, |BOP - BRP|
Devices that have a lower magnetic threshold (VOUT=High) detect magnets at a farther distance. Higher
thresholds (VOUT=Low) generally require a closer distance or larger magnet.

10.1 Absolute Maximum Ratings
Absolute maximum ratings are limited values to be applied individually, and beyond which the
serviceability of the circuit may be impaired. Functional operability is not necessarily implied. Exposure to
absolute maximum rating conditions for an extended period of time may affect device reliability.
