R10-E2-X2-V700 Datasheet
R10-E2-X2-V700 on stock Hiccup Time Constant The hiccu p ci rcuit (at the'd elay' pin) provides overload p rotection for the solution. The threshold of the hiccu p mode is determined by the value of RSENSE, When >50mV is developed across the sense resistor, the hiccup circuit is triggered, inhibiting the device. PROTECTING THE DEVICE AGAINST REVERSE BATTERY The simplest way to protect the device against a continuous reverse battery voltage (-26V) is to insert a Schottky diode between GND pin and ground, as shown in the typical application circuit The consequences of the voltage drop across this diode are as follows: If the input is pulled to power GND, a negative voltage of -Vf iS seen by the device. (ViI, Vih thresholds and Vstat are increased by Vf with respect to power GND). The undervoltage shutdown level is increa- sed by Vf. If there is no need for the control unit to handle external analog signals referred to the power GND, the best approach is to connect the reference potentialof the control unit to node [6] (see application circuit in fig. 4), which becomes the common signal GND for the whole control board avoiding shift of Vih, ViI and Vstat. This solution allows the use of a standard diode. |
