Description
The ST662A is a regulated charge pump DC-DC
converter. It provides 12 V ± 5 % output voltage to
program byte-wide Flash memory, and can supply
30 mA output current from input as low as 4.75 V.
A logic controlled shut down pin that interfaces
directly with microprocessor reduces the supply
current to only 1 µA.
The ST662AB is available as Automotive Grade in
SO-8 package, whose commercial Part Number is
shown in the
Table 1
(device summary). This
device is qualified according to the specification
AEC-Q100 of the Automotive market, in the
temperature range -40 °C to 125 °C, and the
statistical tests PAT, SYL, SBL are performed.
