| Description | of each pin can be found in the Functional Pin Description section beginning on page 10. Pin Number Pin Name Pin Function Formal Name Definition 1 GND Ground 2 SI Input 3 SCLK Input 4 CS Input Ground SPI Slave In Serial Clock Chip Select Ground for logic, analog, and switch to battery inputs. SPI control data input pin from the MCU to the 33. |
| Features |
a 22-to-1 analog multiplexer for reading inputs as analog. The analog input signal is buffered and provided on the AMUX output pin for the MCU to read.
The 33972 device has two modes of operation, Normal and Sleep. Normal mode allows programming of the device and supplies switch contacts with pull-up or pull-down current as it monitors switch change of state. The Sleep mode provides low quiescent current, which makes the 33972 ideal for automotive and industrial products requiring low sleep-state currents.
Features
• Designed to operate 5.5 V VPWR 26 V • Switch input voltage range -14 V to. |
