AH375 Datasheet | Anachip

Single Phase Hall Effect Latch - Features - 2.2V to 20V DC operation voltage - Temperature pensation - Wide operating voltage range - Open drain pre-driver - 25m A maximum sinking output current - Package: SIP3, SOT23 - General Description AH375 is an integrated Hall effect latched sensor designed for electronic mutation of brush-less DC motor applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a parator that amplifies the Hall voltage, and a schmitt trigger to provide switching hysteresis for noise rejection, and open drain output. An internal bandgap regulator is used to provide temperature pensated supply voltage for internal circuits and allows a wide operating supply 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 - Brush-less DC Motor - Brush-less DC Fan - Revolution counting - Speed measurement - Pin Assignments - Pin Descriptions Name Vdd GND OUT P/I/O P P O Pin # 1 2 3 Description Positive Power Supply Ground Output Pin (Top view) 1 : Vdd 1 3 2 : GND 3 : OUT (SOT23 package) 1 2 3 (SIP package) - Ordering Information AH375 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 : Tape &...
