Functional Blocks

Block name

Function

HE

Hall Elements. These detect X/Y-compositions of flux which is parallel to the IC

package surface by using magnetic concentrator.

PreAmp

This is able to amplify signals from Hall elements.

Angle Detection

&

Sine Wave ROM

Angle Detection makes digital angle data from signals from Hall Elements using Sine

Wave ROM.

DAC

Digital to analog converter for angle output.

PIN Description

No.

Function

1

TSTB

I/O

Analog/Digital

TEST dedicated PIN, which should be connected to the GND in

use.

2

VSS

-

Power

Ground PIN.

3

PDN

I

Analog

Power down PIN. IC is active in the case that PDN is High. IC is

power down in the case that PDN is Low.

4

AOUT

O

Analog

Analog output PIN for angle data. CL: max.200pF（pull-down）

5

VDD

-

Power

Power Supply PIN. 0.1uF Ceramic Capacitor is required between

Vss for stabilization. If Capacitor has magnetism, separate it

around 10mm from IC.

6

TSTA

I/O

Analog

TEST dedicated PIN, which should be connected to the GND in

use.

Application Circuit

*Bypass capacitor must be inserted between VDD and VSS.
