OH13 Hall Effect Latch IC
General Description
Part No：OH13 Operate temperature：-40～150℃ Package：1000pcs/reel

OH13 Hall effect Latching Switch IC integrates hall element and signal processing circuit in one silicon chip, including a reverse protector, voltage regulator, Hall voltage generator, differential amplifier, Schmitt trigger and an open-collector output. It can work with the multi-polar magnetic ring and alternating magnetic fields. OH13 has better anti-interference ability and the output waveform duty ratio is little affected by external temperature and alternating magnetic field.

Features
 High reliability
 High sensitivity
 Good temperature performance
 Anti-environmental stress
Applications
 The brushless DC motor internal reversing
 The motor speed and direction detection
 The motor of electric bicycle, power assisted device
 Speed sensor, counter
 The flow sensor, flow meter

Precautions of OH Series Hall ICS
Hall ICs are sensitive devices which performance could be influenced in some extent by magnetic, optical, thermal and mechanical stress.
1) A pull-up resistor RL should be connected between the power supply (Vcc) and the output (Vout) since most of hall ICs are open collector output (OC output) circuits, such as OH44E, OH137, OH513, OH543. Hall ICs with Build-in Resistor are not necessary to add one, for example OH921.
2) Avoid reversing the power supply (Vcc) and the output (Vout) as well as no overload use. Be careful of the burn and damage caused by instant large current and instantaneous high voltage.
3) The Protection circuit should be added in the test circuits of hall ICs, such as large capacitor and a voltage stabilizing diode, which could absorb the effects of the external circuit and power fluctuation.
4) Try to minimize the mechanical stress applied to the device and leads during the installation, especially on the pins where close to the root of the device when bending shaping etc.
5) Strictly regulate the welding temperature and time. When manual welding, the temperature of soldering iron shall not exceed 260℃and time should be less than 3 seconds.
6) When designing, please fully consider the influence factors of temperature, magnetic field attenuation, the movement way, etc.
