REV 1.0 FEATURES and FUNCTIONAL DIAGRAM · · · · · · · · Enhanced sensitivity: will operate from only 45 Gauss typical, at 25°C allowing the use of smaller, potentially lower-cost magnets or wider air gaps Subminiature, SOT-23-3L(CH421S) or SOT-89-3L(CH421E) 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 (CH421T) 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 PACKAGE TO-92S SOT-23-3L SOT-89-3L APPLICATIONS Transportation - Speed and RPM (revolutions per minute) sensing - Tachometer, counter pickup - Motor and fan control - Electric window lift - Convertible roof position - Automotive transmission position Industrial - Speed and RPM sensing - Tachometer, counter pickup - Flow-rate sensing - Brushless dc (direct current) motor commutation - Motor and fan control - Robotics control Medical - Motor assemblies - Medication dispense control DESCRIPTION The CH421S ,CH421E and CH421T 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 CH421S in the subminiature SOT-23-3L surface mount package, the CH421E in the subminiature SOT-89-3L surface mount package, and the CH421T in the leaded, flat TO-92S package. The CH421S’s and CH421E’s small size requires less PC board space, allowing it to be used in smaller assemblies. Its 3V capability allows for use in low voltage applications, promoting energy efficiency. The CH421S and CH421E are available on tape and reel; the CH421T is available in a bulk package (1000 units per bag). Page 1/10 PDF
