In order to avoid this case, connect a bypass capacitor across IN terminal and GND terminal of IC. 1μF or higher is recommended. Pull up /OC output by resistance 10kΩ to 100kΩ. Set up value which satisfies the application as CL. This application circuit does not guarantee its operation. When using the circuit with changes to the external circuit constants, make sure to leave an adequate margin for external components including AC/DC characteristics as well as dispersion of the IC. Functional Description 1. Switch operation IN terminal and OUT terminal are connected to the drain and the source of switch MOSFET respectively. And the IN terminal is used also as power source input to internal control circuit. When the switch is turned on from EN/EN control input, IN terminal and OUT terminal are connected by a 80mΩ switch. In on status, the switch is bidirectional. Therefore, when the potential of OUT terminal is higher than that of IN terminal, current flows from OUT terminal to IN terminal. Since a parasitic diode between the drain and the source of switch MOSFET is not present in the off status, it is possible to prevent current from flowing reversely from OUT to IN. 2. Thermal shutdown circuit (TSD) Thermal shut down circuit have dual thermal shutdown threshold. Since thermal shutdown works at a lower junction temperature when an over-current occurs, only the switch of an over-current state become off and error flag is output. Thermal shut down action has hysteresis. Therefore, when the junction temperature goes down, switch on and error flag output automatically recover. However, until cause of junction temperature increase such as output shortcircuit is removed or the switch is turned off, thermal shut down detection and recovery are repeated. The thermal shut down circuit works when the switch of either OUT1 or OUT2 is on (EN,/EN signal is active). www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.

Over-current detection (OCD) The over-current detection circuit limits current (ISC) and outputs error flag (/OC) when current flowing in each switch MOSFET exceeds a specified value. There are three types of response against over-current. The over-current detection circuit works when the switch is on (EN,/EN signal is active). 3-1. When the switch is turned on while the output is in short-circuit state When the switch is turned on while the output is in short-circuit status, the switch goes into current limit status immediately. 3-2. When the output short-circuits while the switch is on When the output short-circuits or high-current load is connected while the switch is on, very large current flows until the over-current limit circuit takes into action. When the current is detected, limiter circuit works, current limitation is carried out. 3-3. When the output current increases gradually When the output current increases gradually, current limitation does not work until the output current exceeds the over-current detection value. When it exceeds the detection value, current limitation is carried out. 4. Under-voltage lockout (UVLO) UVLO circuit prevents the switch from turning on until the VIN exceeds 2.3V(Typ.). If the VIN drops below 2.2V(Typ.) while the switch turns on, then UVLO shuts off the switch. UVLO has hysteresis of 100mV(Typ). Under-voltage lockout circuit works when the switch of either OUT1 or OUT2 is on (EN,/EN signal is active). 5. Error flag (/OC) output Error flag output is N-MOS open drain output. At detection of over current or thermal shutdown, the output level is low. Over-current detection has delay filter. This delay filter prevents instantaneous current detection such as inrush current at switch on, hot plug from being informed to outside.

The damage can either be a short circuit between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. (2) Recommended operating conditions These conditions represent a range within which the expected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. (3) Reverse connection of power supply Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply terminals. (4) Power supply lines Design the PCB layout pattern to provide low impedance ground and supply lines. Separate the ground and supply lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. (5) Ground Voltage The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that no pins are at a voltage below the ground pin at any time, even during transient condition. (6) Short between pins and mounting errors Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong orientation or if pins are shorted together. Short circuit may be caused by conductive particles caught between the pins. (7) Operation under strong electromagnetic field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. (8) Testing on application boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. (9) Regarding input pins of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a parasitic diode or transistor. For example (refer to figure below): When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided.

Also ensure that the GND traces of external components do not cause variations on the GND voltage. The power supply and ground lines must be as short and thick as possible to reduce line impedance. (11) External Capacitor When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with temperature and the decrease in nominal capacitance due to DC bias and others. (12) Thermal shutdown circuit (TSD) The IC incorporates a built-in thermal shutdown circuit, which is designed to turn off the IC when the internal temperature of the IC reaches a specified value. Do not continue to operate the IC after this function is activated. Do not use the IC in conditions where this function will always be activated. (13) Thermal consideration Use a thermal design that allows for a sufficient margin by taking into account the permissible power dissipation (Pd) in actual operating conditions. Consider Pc that does not exceed Pd in actual operating conditions (Pc≥Pd).
