11 / 20 page  Precision Hall Effect Angle Sensor IC with I2C Interface A1332 10 Allegro MicroSystems, LLC 115 Northeast Cutoff Worcester, Massachusetts 01615-0036 U.S.A. 1.508.853.5000; www.allegromicro.com APPLICATION INFORMATION The A1332 features an I2C compliant interface for communica- tion with a host microcontroller, or Master. A basic circuit for configuring the A1332 package is shown in Figure 4. It is recom- mended that both the SCL and SDA lines be tied to 3.3 V via a 1 kΩ pull-up resistor. If using a Pull-Up voltage of 5 V, it is recommended to limit current by using a higher value pull-up resistance that 1 K. Serial Interface Description If the SDA pin is tied to 5 V, instead of 3.3 V, this results in the forward biasing of an internal diode in the A1332 which could conduct current into the digital voltage regulator internal to the device. This may result in degraded voltage regulation per- formance. Current- limiting resistors have been implemented on-chip to limit this effect. Measurements show that exposure to this condition does not damage the IC in any permanent manner. However, for best results, it is recommended that the Serial Logic pins SDA and SCL be tied to 3.3 V and not 5 V VCC. 3.3 V Internal Regulator 3.3 V Internal Regulator 3.3 V External Supply 5 V External Supply SDA Pin SDA Pin Pull-Up Resistor Pull-Up Resistor Internal Resistor Internal Resistor Digital Sub-System Digital Sub-System Current Flows from VCC into 3.3 V Internal Regulator. Regulator may suffer some degradation in performance. A1332 will continue to function with the 5 V SDA Pull-Up, but this is not a desirable conigur- ation.
