GATE
Gate Drive Output: This pin is the output of an internal charge pump connected to the gate of an
external, N-channel power MOSFET. The charge pump has been designed to provide a minimum
gate drive (V
GATE
= V
GATE
- V
CC
) of +7.5V over the input supplys full operating range. When the
ON pin voltage is higher than the V
ONH
threshold, a 16礎 current source (I
GATEON
) charges the
GATE pin.
When in current limit, the output voltage at the GATE pin is adjusted so that the voltage across
the external sense resistor is held equal to V
TRIP
while the capacitor connected to the TIMER pin
charges. If the current-limit condition goes away before the TIMER pin voltage rises above the
V
TIMERH
threshold, then steady-state operation resumes.
The GATE output pin is shut down whenever: (1) the input supply voltage is lower than the V
UVL
threshold, (2) the ON pin voltage is lower than the V
ONL
threshold, (3) the TIMER pin voltage is
higher than the V
TIMERH
threshold, or (4) the difference between the VCC and SENSE pins is
greater than V
TRIP
while the TIMER pin is grounded. For cases (3) and (4) overcurrent fault
conditions the GATE is immediately pulled to ground by I
GATEFLT
, a 30mA (minimum) pulldown
current.
13
SENSE
Circuit Breaker Sense Input: This pin is the (-) Kelvin sense connection for the output supply rail.
A low-valued resistor (R
SENSE
) between this pin and the VCC pin sets the circuit breakers current
limit trip point. When the current limit detector circuit is enabled (as well as the current-limit timer),
while the FB pin voltage remains higher than 1V, the voltage across the sense resistor (V
CC
-
V
SENSE
) will be regulated to V
TRIP
(47mV, typically) to maintain a constant current into the load.
When the FB pin voltage is less than E0.8V, the voltage across the sense resistor decreases
linearly to a minimum of 12mV (typical) when the FB pin voltage is at 0V.
To disable the circuit breaker (and defeat all current limit protections), the SENSE pin and the
VCC pin can be tied together.
14
VCC
Positive Supply Voltage Input: This pin is the (+) Kelvin sense connection for the output supply
rail. The nominal operating voltage range for the MIC2586 and the MIC2586R is +10V to +80V,
and VCC can withstand input transients up to +100V. An undervoltage lockout circuit holds the
GATE pin low whenever the supply voltage to the MIC2586/MIC2586R is less than the V
UVH
threshold.
