SX8120/21
1V Motor/LED control timer
ADVANCED COMMUNICATIONS & SENSING
DATASHEET
Description
The SX8120/21 is a series of 1 V motor/LED control
timers.
The SX8120/21 goes active on the press of a button.
The output goes back to sleep on the next button
press or after a preset time-out (15 sec or 30 sec on
SX8120, 10 minutes or never on the SX8121). The
time-out duration and the motor control polarity are
pin-selected.
When the SX8120/21 is active, it sets its MOTOR
control pin to high or low and sends a burst on its
LED pin to control a LED or boost a command
voltage.
One output goes low when VDD is higher than the
full charge voltage of an NiMH cell to control a
minimal charger.
The SX8120/21 controls its IO state starting at 0.6V to
