Introduction
The CH424 and CH424N are small, versatile digital Hall effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet, designed to respond to alternating North and South poles. These bipolar latching sensor ICs have enhanced sensitivity, which often allows for the use of less expensive magnets. These sensor ICs are available in three package styles, the CH424S/CH424NS in the subminiature SOT-23-3L surface mount package, the CH424E/CH424NE in the subminiature SOT-89-3L surface mount package, and the CH424T/CH424NT in the leaded, flat TO-92S package. The CH424S/CH424NS's and CH424E/CH424NE's small size requires less PC board space, allowing it to be used in smaller assemblies. Its 3.3V capability allows for use in low voltage applications, promoting energy efficiency. The CH424S/CH424NS and CH424E/CH424NE are available on tape and reel; the CH424T/CH424NT is available in a bulk package (1000 units per bag).
Features
- Enhanced sensitivity: will operate from only 30 Gauss typical, at 25°C allowing the use of smaller, potentially lower-cost magnets or wider air gaps
- Subminiature, SOT-23-3L(CH424S/CH424NS) or SOT-89-3L(CH424E/CH424NE) surface mount package supplied on tape and reel allows for a compact design with automated component placement, helping to reduce manufacturing costs
- Small, leaded, flat, TO-92S package (CH424T/CH424NT) allows for a compact PCB layout
- Bipolar latching magnetics respond to alternating North and South poles, making these products well-suited for accurate speed sensing and RPM (revolutions per minute) measurement
- Wide operating voltage range of 3.3V to 30V makes these sensors useable in a wide range of applications
- Built-in reverse voltage capability enhances the protection of the sensor and the circuits with which it is used
- Robust design: will operate up to 150°C
- RoHS-compliant material meets directive 2011/65/EU
Applications
