RESET RESET RESET RESET 7 Lead 24 Lead * 14 Lead TO-220 SOIC Wide PDIP 121 12 VIN Supply voltage to IC, usually direct from the battery. 2 23 13 ENABLE CMOS compatible logical input. VOUT is disabled when ENABLE is LOW and WDI is beyond its preset limits. 3 24 14 CMOS compatible output lead. goes low whenever VOUT drops below 4.5% of its typical value for more than 2µs or WDI signal falls outside itÕs window limits. 4 12, 20 11 Gnd Ground connection. 5 2 1 Delay Timing capacitor for Watchdog and functions. 6 3 2 WDI CMOS compatible input lead. The Watchdog function mon- itors the falling edge of the incoming digital pulse train. The signal is usually generated by the system microprocessor. 74 3 VOUT Regulated output voltage, 5V (typ). N/A 5 4 Sense Kelvin connection which allows remote sensing of output voltage for improved regulation. 1,6-11,13-19,22 5-10 NC No connection. * The CS8141 uses a fused lead package. Leads 6-8 and 17-19 are fused together through the lead frame. These leads are electrically connected to IC ground and should be connected to system ground for a good thermal connection.
