data sheet adp196 rev. 0 | page 9 of 12 theory of operation the adp196 is a high - side nmos load switch controlled by an internal charge pump. the adp196 is designed to operate with power supply voltages from 1.8 v to 5 . 5 v. an internal charge pump biases the nmos switch to achie ve a relatively constant, ultra low on resistance of 1 0 m? across the entire input voltage range (6- ball wl csp package ) . the use of the internal charge pump also allows for controlled turn - on times. t urning t he nmos switch on and off is controlled by the enable input , en, which is capable of interfacing direct ly to 1. 2 v logic signals. gnd en vin vout 10704-022 charge pump overcurrent and slew rate control overtemperature protection qod adp196-01 only figure 21 . functional block diagram the adp196 supports 3 a of continuous current as long as t j is less than 70 c . at 85 c, the rated current d ecrease s to 2.22 a. overcurrent protection limits the output current to 4 a. the ov er temperature protection circuit is activat ed if the load current causes the junction temperature to exceed 125 c . when this occurs, the o ver temperature protection circuit ry disable s the output until the junction temperature falls below approximately 110c , at which point the output is reenabled. if the fault condition persists, the output cycle s off and on until the fault is removed. additional protection is provided by an overcurrent limit that forces the device into a constant current mode of operation. the adp196 - 01 incorporates a quick output discharge ( qod) circuit to discharge the output capacitance when the adp196 - 01 output is disabled . esd protection structures are shown in the block diagram as zener diodes (see figure 21 ). the adp196 is a low quiescent current device with a nominal 4 m? pull - down resistor on its enable pin (en) . t he adp196 is available in a space - saving 1. 0 mm 1. 5 mm , 0 .5 mm pitch, 6- ball wlcsp and a tiny 2.0 mm 2.0 mm 0.55 mm, 0.65 mm pitch, 6 - lead lfc s p.
adp196 data sheet rev. 0 | page 10 of 12 applications informa tion capacitor selection output capacitor the adp196 is designed for operation with small, space -saving ceramic capacitors but functions with most commonly used capac itors when the effective series resistance (esr) value is carefully considered . the esr of the output capacitor affects the response to load transients. a typical 1 f capacitor with an esr of 0.1 ? or less is recommended for good transient response. using a larger value of output capacitance improve s the transient response to large changes in load current. input bypass capacitor connec ting at least 1 f of capacitance from vin to gnd reduces the circuit sensitivity to the pcb layout, especially when high source impedance or long input traces are encountered. when more than 1 f of output capacitance is required, increase the input capac itance to match it. ground current the major source of ground c urrent in the adp196 is the internal cha rge pump for the fet drive circuitry. figure 22 shows the typical ground current when v en = v in and varies from 1 .8 v to 5.5 v. 0 5 10 15 20 25 30 35 40 45 50 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 ground current ( a) v in (v) 10704-023 50ma 100ma 200ma 500ma 1000ma 3000ma figure 22 . ground current vs. input voltage (v in ) for different load current s enable feature the adp196 uses the en pin to enable and disable t he vout pin under normal operating conditions. as shown in figure 23, when a rising voltage (v en ) on the en pin crosses the active threshold , vout turns on. when a falling voltage (v en ) on the en pin crosses the in active threshold, vout turns off. 0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 0 0.2 0.4 0.6 0.8 1.0 1.2 v out (v) enable vo lt age (v) v en falling v en rising v out at 3.6v 10704-024 figure 23 . typical en pin operation as shown in figure 23 , the en pin has built - in hysteresis. th e hysteresis prevents on/off oscillations that can occu r due to noise on the en pin as it passes through the threshold points. the en pin active/inactive thresholds are derive d from the v in voltage; therefore, these thresholds vary with changing input voltage. figure 24 shows the typical en active/inactive thresholds when t he input voltage varies from 1.8 v to 5.5 v. 0 0.2 0.4 0.6 0.8 1.0 1.2 1.8 2.2 2.6 3.0 3.4 3.8 4.2 4.6 5.0 5.4 enab le t hr eshold (v) input voltage (v) en rise en fall 10704-025 figure 24 . typical en thresholds vs. input voltage (v in )
data sheet adp196 rev. 0 | page 11 of 12 timing turn - on delay is defined as the interval between the time that v en exceeds the rising threshold voltage and when v out rises to ~10% of its final value. the adp196 incl udes circuitry that has a typical 2 m s turn - on delay a nd a controlled rise time to li mit the v in inrush current. as shown in figure 25 and figure 26, the turn - on delay is nearly in dependent o f the input voltage . ch1 20ma ? ch2 1v m1ms a ch2 1.18v 1 t 10.6% b w ch3 500mv b w 10704-026 b w t v out input current enable 2 3 figure 25 . typical turn - on time and inrush current, v in = 1.8 v, c out = 47 f, 330 load ch1 20ma ? ch2 1v m1ms a ch2 1.18v 1 t 10.6% b w ch3 2v b w 10704-027 b w t v out input current enable 2 3 figure 26 . typical turn - on time and inrush current, v in = 5 v, c out = 47 f, 330 load the rise time is defined as the time it takes the output voltage to rise from 10% to 90% of v out reaching its fina l value. th e rise time is dependent on the rise time of the internal charge pump. for very large values of output capacitance, the rc time constant ( where c is the load capacitance , c load , and r is the rds on ||r load ) can bec ome a factor in the ri se time of the output voltage. because rds on is much smaller than r load , an adequate approximation for rc is rds on c load . an input or load capacitor is not requir ed for t he adp196 ; however, capacitors can be used to suppress noise on the board. the turn - off time is defined as the time it takes for the output voltage to fall from 90% to 10% of v out reaching its final value. the turn - off time is also dependent on the rc time constant of the output capacit ance and l oad resistance. figure 27 shows typical turn - off time s with v in = 1.8 v to 5 v , c out = 47 f, a n d r load = 330 . 0 1.0 2.0 3.0 4.0 5.0 6.0 0 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 0.10 time ( sec) v out (v) v en v in = 5.0v v in = 3.3v v in = 1.8v 10704-028 figure 27 . typical turn - off time current - limit and thermal ov erload protection the adp196 is protected against damage due to excessive power dis sipation by current - limit and thermal overload protection circuits. the adp196 is designed to limit current when the output load reaches 4 a (typical). when the output load exceeds 4 a, the output voltage is reduced to maintain a constant current limit. thermal overload protection is included, which limits the junction temperature to a maximum of 125c (typical). under extreme conditions (that is, high ambient temperature and/or high power dissipa tion) when the junction temperature starts to rise above 125c, the output is turned off, reducing the output current to zero. when the junction temperature fall s below 110c, the output is turned on again, and the output current is restored to its operati ng value. consider the case where a hard short from vout to ground occurs. at first, the adp196 current limits so that only 4 a is conducted into the short. if self - heating of the junction is gre at enough to cause its temperature to rise above 125c, thermal shutdown is activate d , turning off the output and reducing the output current to zero. as the junction temperature cools and fall s below 110c, the output turns on and conducts 4 a into the sh ort, again causing the junction temperature to rise above 125c . this thermal oscillation between 110c and 125c causes a current oscillation between 4 a and 0 ma that continues as long as the short remains at the output. current - limit and thermal overloa d protections are intended to protect the device against accidental overload conditions. for reliable operation, device power dissipation must be externally limited so that the junction temperature does not exceed 125c.
