The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance taken into consideration by increasing board size and copper area so as not to exceed the maximum junction temperature rating. (Note 1) Internally limited by output clamp voltage. (Note 2) Internally limited by fixed over current limit. (Note 3) Maximum active clamp energy using single pulse of IOUT(START) = 2 A and VBB = 14 V. When IC is turned off in the condition that inductive load is connected, the OUT pin is fell below 0 V. This energy is dissipated by BV2HD070EFU-C. This energy can be calculated with following equation: 𝐿 𝑉 𝑅 𝐸 𝐵𝐵 − 𝑉𝐷𝑆 𝐿 × 𝐼𝑂𝑈𝑇(𝑆𝑇𝐴𝑅𝑇) 𝐴𝑆 = 𝑉𝐷𝑆 × × [ × 𝑙𝑛 (1 − ) + 𝐼 𝑅 𝑂𝑈𝑇(𝑆𝑇𝐴𝑅𝑇)] 𝐿 𝑅𝐿 𝑉𝐵𝐵 − 𝑉𝐷𝑆 Following equation simplifies under the assumption of RL = 0 Ω. 1 𝑉 𝐸 2 𝐵𝐵 𝐴𝑆 = × 𝐿 × 𝐼 × ( 1 − ) 2 𝑂𝑈𝑇(𝑆𝑇𝐴𝑅𝑇) 𝑉 𝐵𝐵 − 𝑉𝐷𝑆 (Note 4) Not 100% tested.
