5. A current foldback function is implemented thanks to a systematic -6mV negative offset on the current amplifier inputs which
protects the battery from over charging current under low battery voltage conditions, or output short circuit conditions.
6. The Gate Drive output stage has been optimized for PMosfets with input capacitance equal to Cload. A bigger Mosfet (with input
capacitance higher than Cload) can be used with TSM108, but the gate drive performances will be reduced (in particular when
reaching the Dmax. PWM mode).
7. The given limits comprise the hysteresis (UV
hyst
).
8. It is possible to modify the UVLO and OVLO limits by adding a resistor (to ground or to V
CC
) on the pins UV and OV.
The internal values of the resistor should be taken into account
