RO
Reset output.
Open drain output from undervoltage reset comparator at the adjustable
version (TLE6389-2 GV),
Pull down structure with an internal 20k
pull up resistor to VOUT at the
5V version (TLE6389-2 GV50 and TLE6389-3 GV50).
11
BDS
Buck driver supply input.
Connect a ceramic capacitor between BDS and VS to generate clamped
gate-source voltage to supply the driver of the PMOS power stage.
12
GDRV
Gate drive output.
Connect to the gate of the external P-Channel MOSFET. The voltage at
GDRV swings between the levels of VS and BDS.
13
VS
Device supply input.
Connect a 220nF ceramic cap close to the pin in addition to the low ESR
tantalum input capacitance.
14
CS
Current-sense input.
Connect current-sense resistor between VS and CS. The voltage drop
over the sense-resistor determines the peak current flowing in the buck
circuit. The external MOSFET is turned off when the peak current is
exceeded.
