8.2.2.4 Setting Analog Current Monitor Voltage (IMON) Range

The analog current monitor voltage range can be set using the RIMON resistor whose value can be calculated as:

Equation 14. RIMON Ω=VIMON µVGIMON µA/A × IOUTmax A = 0.5 ×106 95 × 5.5 =957 Ω

Choose nearest 1% standard resistor value as 953 Ω.
