9.2.2.2 EMC Transient Disturbances Test

Due to the severe electrical conditions in the automotive environment, immunity capacity against electrical transient disturbances is required, especially for a high side power switch, which is connected directly to the battery. Detailed test requirements are in accordance with the ISO 7637-2:2011 and ISO 16750-2:2010 standards. The TPS1HC30-Q1 device is tested and certificated by a third-party organization.

(1) Tested both under input low condition and high condition.
(2) The pulse 2-A voltage is 54-V maximum from VBB with respect to ground. A voltage suppressing mechanism must be used to pass Level III. This test was run with an 2-μF capacitor from VBB to ground.
(3) GND pin network is a 1-kΩ resistor in parallel with a diode BAS21-7-F.
(4) Status II: The function does not perform as designed during the test, but returns automatically to normal operation after the test.

(1) Tested both under input low condition and high condition (DIAG_EN, EN, and VBB are all classified as inputs).
(2) Considering the worst test condition, the device is tested without any filter capacitors on VBB and VOUT.
(3) The GND pin network is a 1-kΩ resistor in parallel with a diode BAS21-7-F.
(4) Status II: The function does not perform as designed during the test, but returns automatically to normal operation after the test.
(5) Select a 36-V external suppressor.
