NOTES
1. SWITCHES CONNECTED WITH DOTTED LINES REPRESENT PMU RANGE DATA[2:0] (ADDR[4:0] = 0x0E); WHEN PMU ENABLE D ATA[2] = 0 (ADDR[4:0] = 0x0C), ALL
2. THE EXTERNAL SENSE PATH MUST CLOSE THE LOOP TO ENABLE THE CLAMPS TO OPERATE CORRECTLY.
3. 25mA RANGE HAS ITS OWN OUTPUT BUFFER.
4. 25mA BUFFER WILL BE TRISTATED WHEN NOT IN USE.
