TPS22916: Which power switch to use for 15 V?

Dan Richter

Part Number: TPS22916
Other Parts Discussed in Thread: TPS22810, TPS22811, LM7310

Tool/software:

For my wearable project I assume to use TPS22916BYFPR for switching the Resistor Voltage Divider (RVD) for 3x Zinc-Air (Energizer 675) cell ADC voltage measurement (3x 1.4V = 4.2V).

I am working now on another project and need to measure the car battery voltage which can have up to 15V when charged from an alternator. The RVD will have R1 = 12k, R2 = 3k3. Which power switch to use for 15 V? MCU is at 3.3 V

Hi Dan,

You can consider TPS22810 or TPS22811 (features and current rating different in them) if you don't need reverse current blocking. LM7310 if you need reverse current blocking.
