MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA

Undervoltage Shutdown Requirements
All outputs turn off at some battery voltage below 6.0 V; For
the A version, the low side shutdown at a lower value,

.
however, as long as the level stays above 5.0 V, the internal
logic states within the device are designed to be sustained. This
ensures that when the battery level then rises above 6.0 V, the
device will return to the state that it was in prior to the excursion
between 5.0 V and 6.0 V (assuming that there was no SPI
communication or direct input changes during the event). If the
battery voltage falls to a level below 5.0 V, then the internal
logic is reinitialized and the device is then in the default state
upon the return of levels in excess of 6.0 V.
Output Voltage Clamping
Each output has an internal clamp to provide protection and
dissipate the energy stored in inductive loads. Each clamp
independently limits the drain-to-source voltage to the range
specified in the Power Outputs section of the
