Cosemitech CH441/CH442/CH443/CH444 Automotive Product Group This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice and Cosemitech assumes no obligation for future manufacture of this product. Contact Cosemitech for the latest status. Preliminary Datasheet 1.4 FEATURES and FUNCTIONAL DIAGRAM · · · · · · · · · · · · · AEC-Q100 automotive qualified Digital Bipolar-Latch Hall Sensor Multiple Sensitivity Options (BOP / BRP): +15 / -15 Gauss; +30 / -30 Gauss; +45 / -45 Gauss; +120 / 120 Gauss; Chopper stabilization for stable operate points throughout operating temperature range On board voltage regulator for 2.5V to 22V range Resistant to physical stress Output short-circuit protection Operation from unregulated supply Reverse-battery and freewheeling protection Solid-state reliability Wide Operating temperature range: -40 to 150 oC Small package sizes TO-92S, SOT-23 and SOT-89 RoHS-compliant material meets directive 2011/65/EU PACKAGE TO-92S SOT-23-3L SOT-89-3L APPLICATIONS - Speed and RPM sensing - Tachometer, counter pickup - Flow-rate sensing - Brushless dc (direct current) motor commutation - Motor and fan control - Robotics control DESCRIPTION The CH441/CH442/CH443/CH444 Hall-effect sensor is extremely temperature-stable and stressresistant sensor ICs, especially suited for operation over extended temperature ranges from -40°C to 150°C. Superior high temperature performance is possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device over-molding, temperature dependencies, and thermal stress. The device includes a voltage regulator, Hall-voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short circuit protected open-drain output to sink up to 25 mA. An on-board regulator permits operation with supply voltages of 2.5 to 22 V. The advantage of operating down to 2.5V is that the device can used in 2.5V applications or with additional external resistance in series with the supply pin for greater protection against high-voltage transient events. The CH441/CH442/CH443/CH444 series is latch Hall switch. For the latch mode, there are also invert polarity devices. Normally a south pole of sufficient strength turns on the output; However, for invert polarity devices, a north pole of sufficient strength turns on the output. The CH441/CH442/CH443/CH444 also integrated internal clamps against supply/output transients; output short circuits protection; reverse battery conditions. Three package styles provide a magnetically optimized package for most applications, SOT-23, TO-92S and SOT-89. Each package type is lead (Pb) free (suffix, –T), with a 100% matte-tin-plated lead-frame. Page 1/14
