When VbIN increases from less than VbIN(u) up to VbIN(ucp) = 5 V (typ.) the charge pump is not active and VOUT ≈Vbb - 3 V. 15) See also VON(CL) in circuit diagram on page 9.

Fault conditions are considered as “outside” normal operating range. Protection functions are not designed for continuous repetitive operation. 17) not subject to production test, specified by design. 18) The reverse load current through the intrinsic drain-source diode has to be limited by the connected load (as it is done with all polarity symmetric loads). Note that under off-conditions (IIN = IIS = 0) the power transistor is not activated. This results in raised power dissipation due to the higher voltage drop across the intrinsic drain-source diode. The temperature protection is not active during reverse current operation! To reduce the power dissipation at the integrated R bb resistor an input resistor is recommended as described on page 9.

Consider that when the device is switched off (IIN = 0) the voltage between IN and GND reaches almost Vbb.

If you want measure load currents up to IL(M), RIS should be less than Vbb - 5 V IL(M) / Kilis Note: For large values of RIS the voltage VIS can reach almost Vbb. See also over voltage protection.

Add RIN for reverse battery protection in applications with Vbb above 16V18); recommended value: 1 RIN + 1 RIS + 1 RV = 0.1A |Vbb| - 12V if DS is not used (or 1 RIN = 0.1A |Vbb| - 12V if DS is used). To minimize power dissipation at reverse battery operation, the overall current into the IN and IS pin should be about 120mA. The current can be provided by using a small signal diode D in parallel to the input switch, by using a MOSFET input switch or by proper adjusting the current through R IS and RV. Vbb disconnect with energized inductive load Provide a current path with load current capability by using a diode, a Z-diode, or a varistor. (VZL < 70 V or VZb < 42 V if RIN=0).

Infineon Technologies AG Page 10 2008-Jan-24 Inverse load current operation PROFET V IN OUT IS bb Vbb VOUT - IL R IS VIS VIN - + IIS The device is specified for inverse load current operation (VOUT > Vbb > 0V). The current sense feature is not available during this kind of operation (IIS = 0). With IIN = 0 (e.g. input open) only the intrinsic drain source diode is conducting resulting in considerably increased power dissipation. If the device is switched on (V IN = 0), this power dissipation is decreased to the much lower value RON(INV) * I2 (specifications see page 4).

In most cases VOUT = 0 V after shutdown (VOUT ≠ 0 V only if forced externally). So the device remains latched unless Vbb < VON(SC) (see page 5). No latch between turn on and td(SC). 25) Can be "switched off" by using a diode DS (see page 8) or leaving open the current sense output.
