Detailed Description

FAULT register bit field definitions.

The FAULT register is 32-bit, read-only, and contains per-channel fault flags. Each fault type has an 8-bit field where bit N corresponds to channel N.

Register Layout

Byte	Bits	Field	Description
3	31:24	OCP[7:0]	Per-channel overcurrent flags
2	23:16	HHF[7:0]	Per-channel HIT not reached flags
1	15:8	OLF[7:0]	Per-channel open-load flags
0	7:0	DPM[7:0]	Per-channel plunger movement flags

Clearing Fault Flags

MAX22200: Reading the FAULT register clears all fault flags simultaneously.

MAX22200A (recommended): Selective clear on read. To clear a specific fault bit, read the FAULT register while keeping the corresponding SDI bit HIGH for the channel(s) to clear. Only the bits corresponding to HIGH SDI bits are cleared.

Note

Channel 0 corresponds to the LSB (bit 0) of each fault byte.

Reading the FAULT register also deasserts the nFAULT pin (if no other faults are active).
