The datasheet only mentions Li+. But the MAX20303 supports charging Li Polymer batteries with full-charge voltages between 4.05 and 4.60V (BatReg range).
These are peak-current mode controlled buck converters, so the inductance is always 2.2µH. More importantly, you have to select the inductor based on its saturation current. We always recommend metal alloy…
The RAM pattern should be loaded when the MAX20303 comes out of Off mode or at boot.
To write a pattern to RAM, the user must set HptRamEn(0x31[6]) to high to enable haptic RAM programming mode.
In…
To write data to the RAM:
Write(0x31,0x40)) //sets HptRamEn to enable haptic RAM programming mode
Write(0x28,0x00) //Write the RAM address for sample 0.
Write(0x29,DAT0) //Write MSB of haptic pattern…
The I2C bus of MAX20303 can be reset from the bus contention (SDA is held low) by clock-through method. The procedure is described below:
Step 1: Master tries to send a logic high on the SDA line
…
If the MPC pin is connected to the LED, it can only output high/low, that is LED on/off operation.
If you want to adjust the brightness of the LED, need to connect the LED to the LED pins of the chip…
Q: What would be the result of shorting ‘CHGIN’ to GND?
A: There is no trouble with shorting CHGIN to GND. In fact, the MAX20303 CHGIN is protected against negative voltage up to -5.5V in order to prevent…
Question1: If we are not going to use the buck-boost or the charge pump, what is the appropriate way to terminate the related pins? Do I still need to populate the passive components for these blocks even…
