? semiconductor components industries, llc, 2011 august, 2011 ? rev. 3 1 publication order number: asm1233d/d asm1233d, asm1233d-l, asm1233m low power, 5 v/3.3 v, p reset, active low, open-drain output description the asm1233d ? l/1233d/1233m are voltage supervisors with low ? power, 5/3.3 v p reset, with an active low, open ? drain output. maximum supply current over temperature is 15 a for 3.3 v devices and 20 a for 5 v devices. the asm1233d ? l/1233d/1233m generates an active low reset signal whenever the monitored supply is out of tolerance. a precision reference and comparator circuit monitors power supply (v cc ) level. the tolerances are 5%, 10% and 15%. when an out ? of ? tolerance condition is detected, an internal power ? fail signal is generated which forces an active low reset signal. after v cc returns to an in ? tolerance condition, the reset signal remains active for 350 ms to allow the power supply and system microprocessor to stabilize. the asm1233d ? l/1233d/1233m is designed with an open drain output stage and operates over the extended industrial temperature range. these devices are available in compact sot ? 223, so ? 8 and to ? 92 packages. other low power products in this family include asm1810/11/12/ 15/16/17. features ? low supply current ? 15 a maximum ( 3.6 v), 20 a maximum (5.5 v) ? automatically restarts a microprocessor after power failure ? 350 ms reset delay after v cc returns to an in ? tolerance condition ? active low power ? up reset, 5 k internal pull ? up ? precision temperature ? compensated voltage reference and comparator ? eliminates external components ? low ? cost sot ? 223/so ? 8/to ? 92 packages ? operating t emperature: ? 40 c to +85 c applications ? set ? top boxes ? cellular phones ? pdas ? energy management systems ? embedded control systems ? printers ? single board computers http://onsemi.com pin configurations see detailed ordering and shipping information in the package dimensions section on page 9 of this data sheet. ordering information soic ? 8 8 lead case 751bd reset v cc nc gnd nc nc nc nc asm1233m 1 so ? 8 (top view) to ? 92 asm1233m sot ? 223 4 lead case 318e to ? 92 3 lead case 29 ? 11 sot ? 223 (top view) asm1233d ? l asm1233d gnd reset v cc gnd 1 2 4 3 gnd reset v cc gnd reset v cc 123 123 123 to ? 92 asm1233d ? l asm1233d (top view) 2 3 4 8 7 6 5
