9.2.2.2 AEC Q100-012 Test Grade A Certification

Short-circuit reliability is critical for smart high-side power switch devices. The AEC-Q100-012 standard is used to determine the reliability of the devices when operating in a continuous short-circuit condition. Different grade levels are specified according to the pass cycles. This device is qualified with the highest level, Grade A, 1 million times short-to-GND certification.

Three test modes are defined in the AEC Q100-012 standard. See Table 9-2 for cold repetitive short-circuit test – long pulse, cold repetitive short-circuit test – short pulse, and hot repetitive short-circuit test.

Table 9-2 Tests
Test Items Test Condition Test Cycles
Cold repetitive short-circuit test – short pulse –40°C, 10-ms pulse, cool down 1M
Cold repetitive short-circuit test – long pulse –40°C, 300-ms pulse, cool down 1M
Hot repetitive short-circuit test 25°C, continuous short 1000 hr

Different grade levels are specified according to the pass cycles. The TPS1HC100-Q1device gets the certification of Grade A level, 1 million short-to-GND cycles, which is the highest test standard in the market.

Table 9-3 Grade Levels
Grade Number of Cycles Lots,Samples Per Lot Number of Fails
A > 1000000 3, 10 0
B > 300000 to 1000000 3, 10 0
C > 100000 to 300000 3, 10 0
D > 30000 to 100000 3, 10 0
E > 10000 to 30000 3, 10 0
F > 3000 to 10000 3, 10 0
G > 1000 to 3000 3, 10 0
H 300 to 1000 3, 10 0
O < 300 3, 10 0
