MA7014 (Preliminary) Major Power Technology Co., Ltd. Rev0.2 5th, Mar., 2020 Unipolar Hall Effect Switch GENERAL DESCRIPTION MA7014 is a unipolar Hall-effect sensor IC. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switchi ng hysteresis for noise rejection, and open -drain output. An internal band-gap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. If a magnetic flux density larger than thresh old Bop, OUT is turned on(low). The output state is held until a magnetic flux density reversal falls below Brp causing OUT to be turned off (high). FEATURES - 2.5V to 26V DC Operation Voltage - Temperature Compensation - Wide Operating Voltage Range - Open-Drain Pre-Driver - 25mA Maximum Sinking Output Current. - Low Profile SOT23-3L and SIP-3L(TO-92S) Package( Green and Lead Free ) PIN ASSIGNMENT The packages of MA7014 are SOT23-3L and SIP-3L; the pin assignment is given by: VDD OUT (Top View) GND VDD GND OUT (Top View) SIP-3L SOT23-3L Name Description VDD Supply Voltage OUT Output GND Ground.
