If the outputs of the coil are inadvertently shorted when the device is powered-on, the A has thermal shutdown protection that will disable the outputs as the IC heats up. The reverse battery protection feature and thermal shutdown have proven to be very robust features for assembly plants and for rework at OEM board assembly.
With present finished motor thickness trending toward 1. The A EW package is shown in figure 7. Commutation of the motor is achieved by use of a single Hall element to detect the rotational position of an alternating-pole ring magnet. The device integrates all the necessary electronics. This includes the Hall element circuit used for commutation, the motor control circuitry, and the full output bridge.
This fully integrated single chip solution provides enhanced reliability including reverse battery protection and output short circuit protection and eliminates the need for any external support components besides the standard external 0. An active braking function is available on a third pin that can be used for fast stop-start cycles for caller ID and gaming functions.
The third pin also enables a micropower sleep mode to reduce current consumption for battery management in portable electronic devices. The small footprint and low profile EW package enables extremely thin motor designs. The Allegro A BLDC motor driver is ideally suited to deliver advanced features and packaging in vibration motor applications in portable handsets and other products such as pagers, handheld video game controllers, electronic toothbrushes, and razors.
