AH337 Single Phase Hall Effect Switch Features - 4.2V to 28V DC operation voltage - Temperature compensation - Wide operating voltage range - Open drain pre-driver - 25mA maximum sinking output current. - Package: SIP3, SOT23 General Description AH337 is an switched Hall-Effect IC which is for contactless switching applications. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier that amplifies the Hall voltage, a schmitt trigger to provide switching hysteresis for noise rejection, and an open-drain output. The bandgap regulator allows a wide operating voltage range. If a magnetic flux density larger than threshold Bop, DO is turned on(low). The output state is held until a magnetic flux density reversal falls below Brp causing DO to be turned off (high). Applications - VCD/DVD loader, CD/DVD ROM - Cover detector - Speed measurement - Home appliances - Home safety Pin Assignment 337 Pin Descriptions Name P/I/O P P O Pin # 1 2 3 Description Positive Power Supply Ground Output Pin 2 (Top view) 337 1 : Vdd 1 3 Vdd GND OUT 2 : GND 3 : OUT (SOT23 package) 123 (SIP package) Ordering Information AH337 X - X X X Wafer Body Blank or A~Z : if necessary to specify Package P: SIP3 W: SOT23 Lead L : Lead Free Packing Blank : Bulk A : Spread-leg ammo pack for SIP-3L; Tape & Reel for SOT23 This datasheet contains new product information.
