STGIPL14K60Smart shutdown function
4 Smart shutdown function
The STGIPL14K60 integrates a comparator for fault sensing purposes. The comparator
non-inverting input (CIN) can be connected to an external shunt resistor in order to
implement a simple over-current protection function. When the comparator triggers, the
device is set in shutdown state and both its outputs are set to low-level leading the halfbridge in 3-state. In the common overcurrent protection architectures the comparator output
is usually connected to the shutdown input through a RC network, in order to provide a
mono-stable circuit, which implements a protection time that follows the fault condition.
Our smart shutdown architecture allows to immediately turn-off the output gate driver in
case of overcurrent, the fault signal has a preferential path which directly switches off the
outputs. The time delay between the fault and the outputs turn-off is no more dependent on
the RC values of the external network connected to the shutdown pin. At the same time the
internal logic turns on the open-drain output and holds it on until the shutdown voltage goes
below the logic input lower threshold. Finally the smart shutdown function provides the
possibility to increase the real disable time without increasing the constant time of the
external RC network.

5.1 Recommendations
●Input signal HIN is active high logic. A 85kΩ (typ.) pull down resistor is built-in for each
high side input. If an external RC filter is used, for noise immunity, pay attention to the
variation of the input signal level.
●Input signal LIN is active low logic. A 720 kΩ (typ.) pull-up resistor, connected to an
internal 5 V regulator through a diode, is built-in for each low side input.
●To prevent the input signals oscillation, the wiring of each input should be as short as
possible.
●By integrating an application specific type HVIC inside the module, direct coupling to
MCU terminals without any opto-coupler is possible.
●Each capacitor should be located as nearby the pins of IPM as possible.
●Low inductance shunt resistors should be used for phase leg current sensing.
●Electrolytic bus capacitors should be mounted as close to the module bus terminals as
possible. Additional high frequency ceramic capacitor mounted close to the module
pins will further improve performance.
●The SD/OD signal should be pulled up to 5 V / 3.3 V with an external resistor (see
Section 4: Smart shutdown function for detailed info).
