STK984-091A-E no.a2117-5/7 application circuit note 1. a voltage overshoot with vibration will be occurred dur ing a switching operation due to floating inductance of the power source wiring connected between terminal +b1 and pg. in order that the voltage overshoot between +b1 and pg, +b1 and each ?ubw, each uvw and pg will not exce ed its rating, please minimize wiring inductance by shortening the wiring, also conn ect a snubber circuit close to between +b1 and pg terminals. 2. with the object of the overcurrent protection circuit fail- safe design, inserting a fuse in +b1 line is recommended. 3. there is a 100k ? (typ) pull-down resister connected inside of the signal input terminal. however, in the case of mounting a resister externally to reduce noise due to wi ring, please satisfy the input voltage threshold of this hybrid-ic. 4. terminal diag 1 and diag 2 are the open drain output configuration. please pull up with 4.7k ? resister to 5v power supply. 5. there is a 100k ? (typ) pull-up resister connected inside of the re set terminal. it operates normally in the open- state. when the short-circuit protection operates and latches the output off, th e latched output off can be released by making reset terminal low and re-opened. m u: 12, 13 v: 14, 15 w: 16, 17 diag1: 10 diag2: 11 4.7k ? 4.7k ? 5v(dc) reset: 3 s1: 22 s2: 23 +b1: 20, 21 pg: 18, 19 + +b2: 1 + sg: 2 8 to 18v(dc) ut: 4 vt: 5 wt: 6 ub: 7 vb: 8 wb: 9 microcontroller stk984-091 a -e 2.2 ? f
