Application Diagram Reverse Battery Protection This offset will be increased when more than one device shares the resistor. Power Dissipation during a reverse battery event is equal to: An external resistor RGND is required to adequately protect the device from a Reverse Battery event. The resistor value can be calculated using the following two formulas. 1. RGND ≤ 600 mV / (Id (on) max) 2. RGND ≥ (-VD) / (-Ignd) Maximum (-Ignd) current, which is the reverse GND pin current, can be found in the Maximum Ratings section. Several High Side Devices can share same the reverse battery protection resistor. Please note that the sum of (Id (on) max) of all devices should be used to calculate RGND value. If the microprocessor ground is not common with the device ground, RGND will produce a voltage offset ((Id (on) max) x RGND) with respect to the IN and STAT pins. 2 P D + ǒ* V DǓ ń R GND In the case of high power dissipation due to several devices sharing RGND, it is recommended to place a diode DGND in the ground path as an alternate reverse battery protection method. When driving an inductive load, a 1 kW resistor should be placed in parallel with the DGND diode. This method will also produce a voltage offset of ~600 mV with respect to the IN and STAT pins. This diode can also be shared amongst several High Side Devices. This voltage offset will vary if DGND is shared by multiple devices. www.onsemi.com 13 NCV8460A Vbat 5V V pull −up VD STAT OL R pull −up I V OUT Input GND RL Figure 32. Open Load Detection In Off State OFF State Open Load Detection when the load is connected, the Rpull-up must also not cause the OFF State OL to miss detecting an OL condition when the load is disconnected. A VOUT voltage below the VOL_max (Openload Off State Detection Threshold) maximum value with the load (RL) disconnected needs to be avoided. The following formula shows this relationship: Off State Open Load Detection requires an external pull-up resistor (Rpull-up) connected between VOUT pin and a positive supply voltage (Vpull-up). The external Rpull-up resistor value should be selected to ensure that a false OFF State OL condition is not detected when the load (RL) is connected. A VOUT voltage above the VOL_min (Openload Off State Detection Threshold) minimum value with the load (RL) connected needs to be avoided. The following formula shows this relationship: ǒ R pull*up t ǒV pull*up * V OL_maxǓńOL 1 OL 1 + I LǒOutput Leakage with V OUT + 3.5 VǓ Ǔ V OUT + V pull*upńǒR L ) R pull*upǓ R L t V OL_min Because Id (OFF) may significantly increase if VOUT is pulled high (up to several mA), Rpull-up resistor should be connected to a supply that is switched OFF when the module is in standby.
