000-0059h1012-100 page 16 of 23 SLG59H1012V applications information hfet1 safe operating area explained silego?s hfet1 integrated power controllers incorporate a number of internal protection featur es that prevents them from damaging themselves or any other circuit or subcircuit downstr eam of them. one particular protection feature is their safe operation area (soa) protection. soa pr otection is automatically activated under overpower and, in some cases, under overcurrent conditions. overpower soa is activated if package po wer dissipation exceeds an internal 5w threshold longer than 2.5 ms. hfet1 devices will quickly switch off (open circuit) u pon overpower detection and automatically resume (close) nominal operation once overpower condition no longer exists. one possible way to have an overpower condition trigger soa pr otection is when hfet1 products are enabled into heavy output resistive loads and/or into large load capacitors. it is u nder these conditions to follow carefully the ?safe start-up loading? guidance in the applications section of the datasheet. during an overcurrent condition, hfet1 devices will try to limit the out put current to the level set by the external r set resistor. limiting the output current, however, causes an increased voltage drop across the fet?s channel because the fet?s rds on increased as well. since the fet?s rds on is larger, package power dissipation also increases. if the resultant increase in package pow er dissipation is higher/equal than 5 w for longer than 2.5 ms, internal soa protection will be triggered a nd the fet will open circuit (switch off). every time soa protection is triggered, a ll hfet1 devices will automatically attempt to resume nominal operation after 160 ms. safe start-up condition SLG59H1012V has built-in protection to prevent over-heating during start-up into a heavy load. overloading the vout pin with a capacitor and a resistor may result in non-monotonic v out ramping. in general, under light loading on vout, v out ramping can be controlled with c slew value. the following equation serves as a guide: where t ramp = total ramping time for v out to reach v in v in = input voltage c slew = capacitor value for cap pin when capacitor and resistor loading on vout duri ng start up, the following tables will ensure v out ramping is monotonic without triggering internal protection: safe start-up loading for v in = 22 v (monotonic ramp) slew rate (v/ms) c slew control (nf) 3 c load ( f) r load ( ) 0.5 66.7 500 80 1.0 33.3 250 80 1.5 22.2 160 80 2.0 16.7 120 80 2.5 13.3 100 80 c slew = t ramp v in x 4.9 a x 20 3
000-0059h1012-100 page 17 of 23 SLG59H1012V note 3: select the closest-value tolerance capacitor. setting the SLG59H1012V?s active current limit setting the SLG59H1012V?s input overvoltage lockout threshold as shown in the table below, sel[1,0] selects the v in overvoltage threshold at which the SLG59H1012V?s internal state machine will turn off (open circuit) the power mosfet if v in exceeds the selected threshold. for example, sel[1,1] would be the most appropriate setting for applications where the steady-state v in can extend up to 20 v without causing any damage to the SLG59H1012V since the ic is 29-v tolerant. with an activated SLG59H1012V (on=high) and at any time v in crosses the programmed v in overvoltage threshold, the state machine opens the power switch and asserts the fault pin within tfault low . in applications with a deactivated or inactive SLG59H1012V (v in > v in(uvlo) and on=low) and if the applied v in is higher than the programmed v in(ovlo) threshold, the SLG59H1012V?s state machine will ke ep the power switch open circuited if the on pin is toggled low-to-high. in these cases, the fault pin will also be asserted within tfault low and will remain asserted until v in resumes nominal, steady-state operation. in all cases, the SLG59H1012V?s v in undervoltage lockout threshold is fixed at v in(uvlo) . safe start-up loading for v in = 12 v (monotonic ramp) slew rate (v/ms) c slew control (nf) 3 c load ( f) r load ( ) 1 33.3 500 20 2 16.7 250 20 3 11.1 160 20 4 8.3 120 20 5 6.7 100 20 r set (k ? ) active current limit (a) 95 1 45 2 30 3 23.5 4 13.3 7 sel1 sel0 v in(ovlo) (typ) 00 6 v 0 1 10.8 v 1 0 14.4 v 11 24 v
000-0059h1012-100 page 18 of 23 SLG59H1012V power dissipation the junction temperature of the slg59h1 012v depends on different factors such as board layout, ambient temperature, and other environmental factors. the primary cont ributor to the increase in the junction temperature of the SLG59H1012V is the powe r dissipation of its power mosfet. its power dissipation and the ju nction temperature in nominal operating mode can be calculated using the following equations: where: pd = power dissipation, in watts (w) rds on = power mosfet on re sistance, in ohms ( ? ) i ds = output current, in amps (a) and where: t j = junction temperature, in celsius degrees (c) ja = package thermal resistance, in celsius degrees per watt (c/w) t a = ambient temperature, in celsius degrees (c) in current-limit mode, the SLG59H1012V?s power dissipation can be calculated by taking into account the voltage drop across the power switch (v in - v out ) and the magnitude of the output current in current-limit mode (i acl ): where: pd = power dissipation, in watts (w) v in = input voltage, in volts (v) r load = load resistance, in ohms ( ? ) i acl = output limited current, in amps (a) v out = r load x i acl pd = rds on x i ds 2 t j = pd x ja + t a pd = (v in -v out ) x i acl or pd = (v in ?
