SHUTDOWN_PROTECTION

Used with digital logic to prevent generation of false logic signals when power supply is turned on or turned off, FETs sense +15 V and -15 V supplies and conduct when either supply drops below pinchoff voltage, activating shutdown output. With values shown, shutdown output is disabled when supplies exceed about 4 V, to provide normal operation.-E. Burwen, Power-Supply Monitor Suppresses False Output Signals, EDN Magazine, Nov. 5, 1977, p 110 and 112.
