NAME
FUNCTION
1, 2, 3
VEE
Analog Low-Side Supply Input. Bypass with an external 100V, 47FF capacitor in parallel with a
100V, 0.1FF ceramic capacitance between AGND and VEE.
4
ILIM1
Class 5 Current-Limit Digital Adjust 1. Referenced to VEE. ILIM1 is internally pulled up to the digital
supply. Use ILIM1 with ILIM2 to enable Class 5 operation and to adjust the Class 5 current-limit
value. See the Electrical Characteristics table and Table 3 for details.
5
ILIM2
Class 5 Current-Limit Digital Adjust 2. Referenced to VEE. ILIM2 is internally pulled up to the digital
supply. Use ILIM2 with ILIM1 to enable Class 5 operation and to adjust the Class 5 current-limit
value. See the Electrical Characteristics table and Table 3 for details.
6
2-EVENT
(MAX5984A/
MAX5984B)
2-Event Classification Select. Referenced to VEE. 2-EVENT is internally pulled up to the digital
supply. Leave unconnected to disable 2-Event classification. Force low to enable the 2-Event
classification. See the 2-Event PD Classification section for more details. Change status of this
bit only when the part is in reset state. The MAX5984C/MAX5984D are enabled.
PWMEN
(MAX5984C)
PWM Control Logic Input. Referenced to VEE. PWMEN is internally pulled up to the digital supply.
Leave unconnected to enable the internal PWM to drive the LED pin. Force low to disable the
internal PWM. The MAX5984A/MAC5984B/MAX5984D are enabled.
LSCEN
(MAX5984D)
Load Stability Check Function Select. Referenced to VEE. LSCEN is internally pulled up to the
digital supply. Leave unconnected to enable the load stability check function. Force low to disable
the load stability check function. Change status of this bit only when the part is in reset state.
The MAX5984A is disabled but the MAX5984B/MAX5984C are enabled.
