V + = 48V, VSEN = 65mV
V + = 8V
V + = 12V
V + = 24V
V + = 48V
V + = 24V, VGATE > 32V, CGATE = 1000pF
V + = 24V, VGATE < 2V, CGATE = 1000pF
V + = 24V, (V + – VSENSE ) → 0.1V, CGATE = 1000pF

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Both V + pins (11, 20) must be connected together and both
ground pins (1, 10) must be connected together.
