Sink current
Start-up cycle
ON deasserted, I_GATE > 10µA
V_CC1 = V_CC2 = 5V
ON asserted, V_SENSE2 – V_OUT2
V_CC1 = V_CC2 = 5V
V_CC1 = V_CC2 = 5V Timer charge current
Timer discharge current
V_ON = V_CCX
I_OUT = 1.6mA, V_CC1 = 5V
ON asserted, V_FB1 > 1.25V, V_FB2 > 0.8V
/POR = V_CC1 – 1V
See Timing Diagram (Figure 2)
V_CCx – V_SENSEx = 100mV, C_GATE = 10nF
See Timing Diagram (Figure 3)
V_CCx – V_SENSEx = 50mV, C_FILTER = 0
Note 1.
Note 2.
Note 3.
Note 4.
Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
For the MIC2584, V_GATEWIN is specified only when ON is asserted.
Specification for packaged product only.
