Diodes Incorporated, new AH37XX high-pressure Hall effect latch integrated circuit series provides different working magnetic field thresholds, which can meet multiple applications of motor control, rotational position and speed detection requirements, including control washing machine, dishwasher, refrigerator Iridge, air conditioning, food processing machine, electric tool and heat dissipation fan brushless DC motor; measuring the speed of the motor, pump and flow meter; and non-contact position detection and indexing for printers, scanners and curtains.
The AH37xx family is suitable for 3V to 28V of industrial and consumer products. These devices integrate reverse blocking diodes, Zener clamps on the input or output pins, and output current limits to prevent transients and overload. The wide temperature range and low temperature coefficients from -40 ° C to + 125 ° C ensure that the product is safe and reliable in the switch threshold, while the electrostatic discharge capacity of 6kV makes the device more durable and simplifies the production process.
The new product line provides a variety of magnetic field work selection and release thresholds (BOP and BRP), making the system design more flexible. BOP and BRP sensitivity of AH3772 / 4 and AH3781 / 2 are as high as + 25g / + 40g, respectively.
-25g / -40g; the amphomensity of AH3775 / 6 provides a rated value of + 70 g / + 110 g / -70 g / -110g; the AH3777 is lowered, and the release threshold is + 140g and -140g. These devices also provide designers to provide output settings between the open drain AH377X series and the AH378X device, and their internal pull-up resistor effectively reducing the number of material definitions and saving circuit board dimensions.
AH37XX Hall effect latch integrated circuit utilizes 10μs fast boot time and 3.75 μs fast reaction time to shorten delay time and reduce commutation errors and provide excellence. A intercept stabilizing architecture equipped with a gap regulator ensures stable temperature, minimizing switch point offset and strengthening stress ability. These devices also have good radio frequency noise immunity, further improve overall operation stability.
AH3772, AH3774, AH3777, AH3776, AH3777, AH3781 and AH3782 are all shipped batch. All products offer SOT23 and SIP3 (Bulk and AMMO package) package selection, where AH3774 and AH3775 are added more additional SC59 package.
