AOZ1375DI ECPower™ 23V 18mΩ Bidirectional Load Switch with Over-Voltage and Over-Current Protection General Description Features The AOZ1375DI is a bidirectional current-limited load switch intended for applications that require circuit protections. The device operates from voltages between 3.4V and 23V and features two power terminals, VINT and VBUS, which are rated at 28V Absolute Maximum. When used as source switch, the internal current limiting circuit protects the supply from large load current. The current limit can be set with an external resistor. The back-to-back switch configuration blocks any leakage between VINT and VBUS pins when the device is disabled.  17.8m typical ON resistance  3.4V to 23V operating input voltage  VINT and VBUS are both rated 28V  Bidirectional operation  Reverse blocking to completely isolate VINT and VBUS when disabled  Programmable current limit  Short-circuit protection  Selectable over-voltage protection  Programmable soft start  Under-voltage lockout  Over-voltage lockout  Thermal shutdown protection  ±4kV HBM ESD rating  ±8kV HBM ESD rating for VBUS and VINT  3mm x 3mm DFN-12L package  UL 2367: file no.

It is capable of operating from 3.4V to 23V and rated up to 5A. by comparators that sets the OVP threshold based on the table below: ROVP Resistor Value (1%) OVP Threshold ≤20K 24V 75K 17.4V 137K 10.4V ≥301K 6.4V AOZ1375DI can be operated as bidirectional switch. As a source switch it can pass power from VINT to the VBUS. As a sink switch, it can pass supply from VBUS to VINT. The devices automatically selects power from either VINT or VBUS whichever is higher. The power switch consists of 2 back-to-back connected N-channel MOSFETs. When switch is enabled, the overall resistance between VINT and VBUS is only 17.8mΩ in typical condition, minimizing power lose and thermal dissipation. The back-to-back configuration of switches completely isolates between VINT and VBUS when turned off, preventing leakage between the two pins. Enable The EN pin is the ON/OFF control for the power switch. The device is enabled when EN pin is high and device is not in UVLO lockout state. The EN pin must be driven to a logic high or logic low state to guarantee operation. While disabled, the AOZ1375DI only draws about 2μA supply current. Input Under-Voltage Lockout (UVLO) Programmable Over-Current Protection (OCP) AOZ1375DI implemented current limit to ensure that the current through the switch does not exceed the programmed value. The current passes through the switch is sensed using external sense resistor RSENSE. Current limit is programmed by an external resistor RLIM connected between ILIM and GND. If over-load occur, the internal circuitry will limit the output current based on the value of RLIM. The current limit threshold can be calculated according to equation below for RSENSE=10mΩ: Current Limit  5 Rev. 1.5 July 2021 4 3 2 1 20 1) If the power switch is on, it will be turned off immediately to isolate VINT from VBUS; An external resistor ROVP connected between POVP and GND pins sets the over-voltage protection threshold. An internal 8µA current source biases POVP pin. The voltage drop across resistor ROVP is detected  A 6 The voltages at both VINT and VBUS pins are constantly monitored once the device is enabled. In case voltage on either pin exceeds the programmed threshold, over-voltage protection is activated: In either case FLTB pin is pulled low to report the fault condition. R LIM k  7 Programmable Over-Voltage Protection (OVP) 2) OVP will prevent power switch to be turned on if it is in off state. 160 For example, for 5.3A current limit, a 30kΩ RLIM should be selected. ILIM (A) The internal circuitry of AOZ1375DI is powered from either VBUS or VINT. The under-voltage lockout (UVLO) circuit of AOZ1375DI monitors the voltage at both pins and only allows the power switches to turn on when VINT or VBUS is higher than 3.4V. If both pins are below 3.4V, the device is in under-voltage lockout state. Table 1. OVP Setting by External Resistor 40 60 80 120 100 RLIM (k) Figure 30. Current Limit vs RLIM The current limit threshold should be within 1A to 6A. Current limit accuracy or functionality is not guaranteed beyond this range. 1% resistors are recommended for both RSENSE and RLIM. When AOZ1375DI is under current-limiting, FLTB is pulled low after 500µs delay. The load switch will then open if the device is still current-limiting after an additional 500µs delay. www.aosmd.com Page 11 of 17 AOZ1375DI There is no current limiting function when configured as sink switch (current flow from VBUS to VINT), but VINT startup rise time is still controlled by the SS pin. The actual soft start also depends on the output capacitance and current limit setting if in-rush current reaches current-limit level. If current limit function is not used, both CSP and CSN pins must be connected to VINT. System Startup Short-Circuit Protection (SCP) AOZ1375DI implemented short-circuit protection to quickly turn off the power switch when output is severely overloaded. A comparator monitors the voltage drop between VINT and VBUS when switch is closed. Shortcircuit protection is activated when the above voltage difference reaches approximately 75% of VINT. Shortcircuit protection functions in either sourcing or sinking configuration. The device is enabled when EN≥1.4V and either VBUS or VINT is higher than UVLO threshold. The OVP threshold is first selected by sensing POVP voltage set by ROVP. The device will then check if fault condition exist. When no fault exists, the power switch is turned on and the output is then ramped up, controlled by the soft start and current limiting circuitry till it reaches input voltage. Fault Protection Short-circuit protection is not active until soft start is completed. AOZ1375DI protects its load from the following fault conditions: over-voltage, over-current, short-circuit, and over-temperature. Thermal Shutdown Protection When device is first enabled, the power switch is off and fault conditions are checked. If voltage at VBUS or VINT is higher than the OVP threshold, or die temperature is higher than thermal shutdown threshold. FLTB pin is pulled low to report to host controller. During current limit or short-circuit, the power switch resistance is increased to limit the load current. This increases device power dissipation dramatically and causes the die temperature to rise. When the die temperature reaches 140°C the power switch is turned off. There is a 35°C hysteresis. Over-temperature fault is removed when die temperature drops below approximately 105°C. Soft Start When EN pin is asserted high, the soft start control circuitry applies voltage on the gate of the power switch in a manner such that the output voltage is ramped up linearly until it reaches input voltage level. The soft start can be adjusted by an external capacitor Css connected between SS pin and ground. The soft start can be approximately set by the following equation: t ss  Css 6E  5 s  VIN      n  2.8E  06 A V  where, VIN is in volts and Css is in farads and tss is in seconds. The quantity “n” is a dimensionless number determined according to the following table. The recommended Css value is 1.0nF~1.5nF. The Css should be less than 1.5nF.: n VOVP 24 24V or 17.4V 10.4 10.4V 6.4 6.4V Table 2. n vs. VOVP Rev. 1.5 July 2021 After the power switch turned on, device continuously monitors all fault conditions. The switch is turned off when OVP, short-circuit, or over-temperature is detected. FLTB pin is pulled low. In case of over-current, the device will limit the current pass-through the switch to the value set by RLIM. The switch is turned off if over-current last approximately 1ms. FLTB pin is pulled low about 500µs after OCP is detected. Auto-restart or Latch-off AOZ1375DI-01 (auto-restart version): The device will try to restart 64ms after the power switch is turned off due to fault protection. AOZ1375DI-02 (latch-off version): The device keeps off after fault occurs. It can only be re-enabled by either toggle EN pin or recycle the power. Input Capacitor Selection The input capacitor prevents large voltage transients from appearing at the input, and provides the instantaneous current needed each time the switch turns on to charge output capacitors and to limit input voltage drop. It is also to prevent high-frequency noise on the power line from passing through to the output. The input capacitor should be located as close to the pin as possible. A 10μF ceramic capacitor is recommended. However, higher capacitor values further reduce the transient voltage drop at the input. www.aosmd.com Page 12 of 17 AOZ1375DI Output Capacitor Selection Layout Guidelines The output capacitor has to supply enough current for a large load that it may encounter during system transient. This bulk capacitor must be large enough to supply fast transient load in order to prevent the output from dropping. Good PCB layout is important for improving the thermal and overall performance of AOZ1375DI. To optimize the switch response time to output short-circuit conditions, keep all traces as short as possible to reduce the effect of unwanted parasitic inductance. Place the input and output bypass capacitors as close as possible to the VINT and VBUS pins. The input and output PCB traces should be as wide as possible for the given PCB space. Use a ground plane to enhance the power dissipation capability of the device. For accuracy current limit during source mode operation, RSENSE signal must be Kevin connection to CSP and CSN pin. The sense location for RSENSE should be as close to the resistor terminal as possible to reduce the effect of resistance from PCB trace. Figure 31 shows the evaluation board reference layout. There is an upper limit for output capacitor to ensure it can be charged fully during start-up. This upper limit is set by the current limit level and soft start time. Output Capacitor (Max) = Current Limit * (tON / Input Voltage) If output capacitor is too large that output voltage can’t reach 75% of the input voltage at the end of soft start time, short-circuit protection will be triggered. Power Dissipation Calculation Calculate the power dissipation for normal load condition using the following equation: Power Dissipated = RON × (IOUT)2 The worst case power dissipation occurs when the load current hits the current limit due to over-current or shortcircuit fault. The power dissipation under these conditions can be calculated using the following equation: Power Dissipated = |VINT – VBUS| × Current Limit Figure 31.
