Notes
1. The device will withstand load dump transient as defined by ISO7637 with peak voltage of 80 V.
2. Normal operation of the 33937 at VPWR voltages greater than 28V can result in degradation or failure of the VLS regulator due to
transients induced during a RESET. A 20 V transient suppressor is recommended on the VLS pin (pin 51) to prevent excessive stress
under these conditions. Using the 33937A will avoid this limitation.
3. Short-circuit proof, the device will not be damaged or induce unexpected behavior due to shorts to external sources within this range.
4. This voltage should not be applied without also taking voltage at HS_S and voltage at PX_LS_S into account.
5. Actual operational limitations may differ from survivability limits. The VLS - VLS_S differential and the VBOOT - VHS_S differential must be
greater than 3.0 V to insure the output gate drive will maintain a commanded OFF condition on the output.
