PIN DESCRIPTION
Pin No.
QFN
Pin Type
Name
Description
1,2
I
PD0, PD1
The PD pins are active high, logic level inputs. Protection diodes allow
them to be overdriven when used in conjunction with a series limiting
resistor. The PD pins have an internal pull-down current sink of 10uA
typical.
3
I
RESET#
The RESET# pin is used to clear latched fault conditions. When this pin is
asserted, the VGATEX and PUPX outputs are immediately disabled. Refer to
the section on Circuit Breaker Operation for more information. The RESET#
pin has an internal pull-up current source to 5V_CAP of 10uA typical.
4
I
SCL
SCL is the serial clock input.
5
I/O
SDA
SDA is the bidirectional serial data I/O port.
6,
7,
8,
9
O
PUPA, PUPB,
PUPC,
PUPD
The PUPX outputs are programmable active high/low open drain converter
enable pins. They can be used in one of 4 programmable sequence
positions to switch a load or enable a DC/DC converter after a
programmable delay, tPGDn. The voltage on these pins cannot exceed 12V
relative to VSS.
10
O
FAULT#
FAULT# is an open-drain, active-low output that indicates the fault status of
the device. The device’s Status Register may be polled to determine more
detailed information about the fault condition.
11
PWR
VSS
This is connected to the negative side of the supply.
12
I
CBSENSE
The circuit breaker sense input is used to detect over-current conditions
across an external, low value sense resistor (RS) tied in series with the
Power MOSFET. A voltage drop of greater than VCB (programmable level)
across the resistor for longer than tCBD trips the circuit breaker. A
programmable Quick-Trip™ sense point is also available.
13
I
UV
The UV pin is used as an under-voltage supply monitor, typically in
conjunction with an external resistor ladder. VGATE_HS is enabled when
the UV input > Vuv and disabled when UV < Vuv-Vuvhys. An optional
programmable filter delay is also available on the UV input.
14
I
OV
The OV pin is used as an over-voltage supply monitor, typically in
conjunction with an external resistor ladder. VGATE_HS is disabled when
OV > Vov and enabled when OV < Vov-Vovhys. A filter delay is also
available on the OV input.
15
I
EN/TS
The Enable/Temperature Sense input is the master enable input. If EN/TS
is less than 2.5V, all VGATE outputs are disabled.
16
I
SLEW_CNTL
A capacitor connected to this pin controls the VGATE_HS Slew Rate.
17
I
FEEDB
Connect to the -48V 'B' feed using a series 100k resistor. The voltage on
this pin is compared with the voltage on the FEEDA pin internally by the
supply arbitration logic to determine which voltage will be used.
