GAT2x – Gate drive output for the blocking MOSFET. The blocking MOSFET prevents reverse channel current
when OUTx is higher than INx. This is often used when two input sources are ORed together. GAT2x sources 30
µA to turn the MOSFET on. GAT2x is low when ENx is low, ORENx is low, FLTx is low, a fast trip is active, or a
voltage reversal has occurred. A 10 µs, 1 A, discharge and 14 mA pulldown are applied when this occurs.
An internal clamp prevents this pin from rising more than 14.5 V above OUTx. Setting the ORENx or ENx pins
low holds the GAT2x pin low.
GAT2x may be left open if not used.
INx - Supply pin for the internal circuitry. A small bypass capacitor (e.g. 0.1 µF) is recommended for this pin.
MONx – A resistor connected from this pin to ground forms part of the current limit programming. As the current
delivered to the load increases, so does the voltage on this pin. The current-limit circuit controls GAT1x to limit
channel current at a VMONx of 675 mV. The current limit circuit is inactive for lower values of VMONx.
Equation 1 through Equation 4 define current limit and fast trip values using RMONx, RSENSEx, and RSETx. VMONx
can by sampled with an external A/D converter to measure the channel current.
ORENx – Active high input. Pulling this pin low disables the blocking function by pulling the GAT2x pin low.
Pulling this pin high (or allowing it to float high) allows the blocking function to operate normally. The M2x internal
diode may carry the load current when GAT2x is low and VINX > VOUTX.
An internal 200 k
Ω resistor pulls this pin to VINT. ORENx may be left open when blocking is not used, or does
not require active control.
OUTx – Senses the output voltage of the channel. This voltage is used by the biasing, blocking, and power good
circuits.
PGx – Active low open-drain output. A low on PGx indicates that VOUTx has exceeded 10.63 V, and has not
fallen below 10.50 V. These thresholds are internally set, and modifying the OUTx connection may effect
blocking operation.
SENMx – Senses the voltage on the load side of RSENSEx for use by the fast trip and current limiting circuits.
SENPx – Senses the voltage on the source side of RSENSEx for use by the fast trip and blocking circuits. The fast
trip overcurrent shutdown is activated at a VSENP-SENM of 0.1 V.
SETx – A resistor connected from this pin to SENPx sets the current limit level in conjunction with RSENSEx and
RMONx as described in Equation 1 through Equation 4.
VINT – This pin connects to the internal 2.35 V rail. A 0.1 µF capacitor must be connected from this pin to
ground. VINT is not designed to be a general-purpose bias rail.
