These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
Absolute Maximum Ratings
(1)
VIN to GND -0.3V to 105V
HS to GND
(2)
-5V to 105V
BST1/BST2 to GND -0.3V to 116V
BST1/BST2 to HS1/HS2 -0.3V to 16V
HO1/HO2 to HS1/HS2
(3)

to GND -0.3V to 16V
REF,SSOFF,RT,OVP,UVLO to GND -0.3V to 7V
RAMP -0.3V to 7V
COMP -0.3V
COMP Input Current +10mA
All other inputs to GND
(3)

ESD Rating HBM
(4)
2 kV
Storage Temperature Range -55°C to 150°C
Junction Temperature 150°C
(1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which
operation of the device is intended to be functional. For specifications and test conditions, see Electrical Characteristics.
(2) The negative HS voltage must never be more negative than VCC-16V. For example, if VCC=12V, the negative transients at HS must
not exceed -4V.
(3) These pins are output pins and as such should not be connected to an external voltage source. The voltage range listed is the limits the
internal circuitry is designed to reliably tolerate in the application circuit.
(4) The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
