Maximum ratings are the extreme limits to which the device can be exposed for a limited amount of time without permanently damaging it. Exposure to absolute maximum ratings for prolonged periods of time may affect the reliability of the device.

The operating conditions are the physical parameters that the chip can operate within.

Table 7: Recommended operating conditions

Note: Any system features powered by VSYS will only operate when the VSYS voltage > VSYSPOF.

A global thermal shutdown is triggered when the die temperature exceeds the operating temperature range, see TSD. All device functions are disabled in thermal shutdown. The device functions are re-enabled when the temperature is sufficiently reduced according to a hysteresis TSDHYST. The die temperature limit is only monitored when charging is enabled or when a BUCK is enabled and is in PWM mode.

A secondary mechanism disables the charger when the die reaches the host software programmable temperature of DIETEMPSTOP on page 43 . Once this temperature is reached, charging stops but all other functionality remains active. Charging restarts when the die temperature reaches the host software programmable temperature of DIETEMPRESUME on page 44.
