PIN FUNCTION DESCRIPTION
Pin No.
Mnemonic
Function
1
SENSE
Connection to External FET Source Voltage. A sense resistor is connected in the supply path
between the SENSE Pin and V
EE
, and the voltage across this resistor is monitored to detect current
faults. This voltage is fed as an input to the linear current regulator. When it reaches 100 mV for
a specified period, t
ON
, the regulator reduces the gate voltage and drives the FET as a linear pass
device. If current monitoring is not required, this feature can be turned off by shorting the
SENSE Pin and V
EE
together.
Device Negative Supply Voltage. This pin should be connected to the lower potential of the
power supply.
Shunt Regulated On-Chip Supply, Nominally V
EE
+ 12.3 V. This pin should be current fed
through a dropper resistor that is connected to the higher potential of the power supply inputs.
Allows User Control over Timing Functions by Determining Frequency of Oscillator. Fre-
quency set by connecting external capacitor to V
EE
. Tying pin directly to V
EE
causes oscillator to
default to internally set value.
Input Pin for Overvoltage and Undervoltage Detection Circuitry. The voltage appearing on the
UV/OV Pin is proportional to board supply and is determined by external resistors. When the
voltage on UV/OV falls below the undervoltage threshold of 0.86 V, the GATE Pin is driven low.
When the voltage appearing at the UV/OV Pin rises above the overvoltage threshold of 1.97 V,
the GATE Pin is also driven low. If the external resistor ratio of R1/R2 = 40 is used, then this
gives an operating range of –36 V to –77 V.
Output to External FET Gate Drive. Controlled by linear current regulator. The gate is driven
low if an overvoltage or undervoltage fault occurs or if a current fault lasts for longer than the
time, t
ON
. When in linear regulation, the GATE Pin voltage is controlled as part of the servo loop.
No external compensation is required. When the FET is fully enhanced and the load capacitance
has been charged, the GATE Pin reaches a high level of typically 12 V.
