7. Functional description
7.1 Start-up state
The IC enters the start-up state when the supply voltage on pin VDD increases. In the
start-up state, the high-side power transistor is non-conducting and the low-side power
transistor is switched on. The internal circuit is reset and the capacitor on the bootstrap pin
FS is charged. The start-up state is defined until the value of VDD = the VDD(start) value.
After which the IC switches to the oscillation state.
The circuit enters the start-up state again when the voltage on pin VDD  VDD(stop).
7.2
NWP2081T oscillation state
In the oscillation state, the output voltage of the GL and GH drivers depend on the logical
signals CLK and SD (see Table 3).

7.3 NWP2081T non-overlap time
The external resistor (RSD) on pin SD sets the non-overlap time of the NWP2081T. The
relationship between this resistor value and actual dead-time is listed in Figure 3.
It is essential to add a 10 nF to 100 nF decoupling capacitor across RSD to ensure a noise
immune dead-time system.

7.4 NWP2081T shutdown protection
When the voltage at pin SD is pulled below VIH, the internal sink drivers of the pins GL and
GH are immediately enabled to switch off the external power MOSFETs.
The shutdown comparator has a hysteresis of Vhys(SD) to avoid multiple switching.
Preferably, pin SD is pulled low via a collector of a transistor (see Figure 4) to avoid
loading of this pin (Influences the non-overlap time settings) at normal operation.

testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
