MP5016H 2.7 - 22V, 0.7 - 5A, Current Limit Switch with Over-Voltage Clamp and Reverse Block DESCRIPTION FEATURES The MP5016H is a protection device designed to protect circuitry on the output from transients on the input. The MP5016H also protects the input from undesired shorts and transients coming from the output. During start-up, the inrush current is limited by limiting the slew rate at the output. The slew rate is controlled by the DV/DT pin setting and MODE pin setting. The maximum load at the output is currentlimited. The magnitude of the current limit is controlled by an external resistor from ILIMIT to GND. There is a fixed 2.5A current limit when ILIMIT is floating.

All Rights Reserved. 10 MP5016H – 2.7 - 22V, 0.7 - 5A, PROGRAMMABLE, CURRENT-LIMITED SWITCH OPERATION The MP5016H is designed to limit the inrush current to the load when a circuit card is inserted into a live backplane power source, thereby limiting the backplane’s voltage drop and the dV/dt of the voltage to the load. The MP5016H offers an integrated solution that monitors the input voltage, output voltage, output current, and die temperature, which eliminates the requirement of an external current sense power resistor, power MOSFET, and thermal sense device. Under-Voltage Lockout (UVLO) The MP5016H can be used in a 2.7V to 22V input supply system. There are high-energy transients during normal operation or hot swaps. These transients depend on the parasitic inductance and resistance of the wire and the capacitor at the VCC node. If a power clamp (TVS, Tranzorb) diode is not used, the E-fuse must be able to withstand this transient voltage. The MP5016H integrates a high-voltage MOSFET with up to 22V of continuous voltage and 26V of maximum transient input voltage. The MP5016H also uses a high-voltage circuit for the VCC node to guarantee safe operation. MODE MODE is used to select the output over-voltage protection (OVP) threshold. Three digital inputs are provided for MODE. Drive MODE high to VCC to set the output OVP clamp voltage at 15.2V. Drive MODE low to GND to set the output OVP clamp voltage at 5.75V. Float MODE for no OVP clamp protection. The OVP threshold can also be set by connecting a resistor from MODE to ground. For more details, refer to the Application Information section on page 13. Soft Start (SS) The soft-start time is related to the dV/dt slew rate and input voltage and can be calculated with Equation (1): t_ss(ms) Vin(V) dv/dt (V/ms) (1) Fast Output and Input OVP To protect the downstream load when there is a surge voltage at the input, the MP5016H provides an output OVP function. An accurate and fast comparator monitors the over-voltage condition of the output. If the output voltage rises above the threshold set by MODE, the gate of the internal MOSFETs is pulled down quickly and is regulated to a certain value to keep the output voltage clamped at the OVP threshold. The fast loop response speed keeps the over-voltage overshoot small. Current Limit (ILIMIT) The MP5016H provides a constant current limit, and the current limit can be programmed by an external resistor. The desired current limit is a function of the external current limit resistor and can be approximated with Equation (2): ILIMIT (A) 0.55(V) 3870 RLIMIT (Ω） (2) Where 3870 is the current sense ratio. Once the current limit threshold is reached, the internal circuit regulates the gate voltage to hold the current in the power MOSFET constant. To limit the current, the gate to the source voltage must be regulated from 5V to around 1V. The typical response time is about 15µs. During this period, the output current may have a small overshoot. If the current limit condition lasts longer than 2ms, the IC enters hiccup mode with 2ms of on time and 700ms of off time. The MP5016H allows ILIMIT to be floated during operation. If ILIMIT is floating, the current limit is set at a fixed 2.5A internally. When shorting ILIMIT to GND, the normal current limit is disabled, but the secondary current limit still works. The secondary current limit is set to 8A internally. When the secondary current limit is triggered, the IC shuts down the power MOSFET. The dV/dt slew rate is controlled by an external DV/DT capacitor setting and the MODE setting.

All Rights Reserved. 11 MP5016H – 2.7 - 22V, 0.7 - 5A, PROGRAMMABLE, CURRENT-LIMITED SWITCH Short-Circuit Protection (SCP) If the load current increases rapidly due to a short-circuit event, the current may exceed the current-limit threshold before the control loop can respond. If the current reaches the 8A secondary current limit level, a fast turn-off circuit activates to turn off the power MOSFET. This can help limit the peak current through the switch, keeping the input voltage from dropping too much. The total short-circuit response time is about 1µs. After the MOSFET has switched off, the part restarts. During the restart process, if the short still exists, the MP5016H regulates the gate voltage to hold the current at a normal current limit level. The IC enters hiccup mode with 2ms of on time and 700ms of off time. To prevent safe operating area (SOA) damage during a high input voltage short-circuit protection (SCP) condition, the IC current limit folds back when the power MOSFET VDS voltage is above the typical 11V and the junction temperature is over 110°C. To avoid large input voltage spikes from damaging the IC during SCP entry, it is recommended to use a 22μF minimum input capacitor when VIN is higher than 15V. If the input surge voltage is higher than the 26V absolute voltage, the IC may be damaged. Reverse-Blocking MOSFET Driver The MP5016H has a GATE pin to provide an external N-channel MOSFET gate drive signal for reverse-current protection (RCP). Three events can pull down the GATE voltage: VIN below the under-voltage lockout (UVLO), the enable (EN) voltage below the low level threshold, or thermal shutdown. If any of these conditions occur, GATE sinks the current from the gate of the external MOSFET to initiate a fast turn-off. For 3.3V low input voltage applications, choose an external reverse-blocking MOSFET with a small gate threshold voltage (VGSth < 1.6V) to reduce the voltage drop caused by the reverseblocking MOSFET. Setting an appropriate OVP threshold can also protect the reverse voltage (from the output to the input) when using an external N-channel MOSFET. When VOUT rises too high during normal operation, the MP5016H SOURCE MP5016H Rev.1.0 5/25/2017 voltage is higher than the OVP threshold. In this case, the GATE voltage is regulated to maintain the SOURCE clamped at the OVP threshold. This action protects the reverse current from the high VOUT to the low VIN. A 100pF capacitor is required on GATE if it is not connected to the external MOSFET. Output Discharge The MP5016H involves a discharge function that provides a resistive discharge path for the external output capacitor. The function is active when the part is disabled (VIN UVLO, EN shutdown) and is done in a very limited amount of time. When using the external reversecurrent block MOSFET, the output discharge path is blocked by the reverse current block MOSFET. Therefore, the output cannot be discharged when the reverse-current block MOSFET is used. Enable (EN) The MP5016H is enabled when EN is high. The MP5016H is disabled when EN is low. Floating EN shuts down the MP5016H because there is an internal 2.2MΩ resistor pulling EN down to ground. For automatic start-up, connect a pullup resistor from VCC to EN. EN is clamped internally using a 5.5V Zener diode (see Figure 2). Connecting the EN input through a pull-up resistor to VCC limits the EN input current below 100μA to prevent damage to the Zener diode. For example, when connecting a 300kΩ pull-up resistor to 22V VCC, IZener = (22V - 5.5V) / 300kΩ - 5.5V / 2.2MΩ = 53µA. EN 1kΩ 2.2MΩ GND 5.5V EN Logic Figure 2: Zener Diode between EN and GND When using a pull-up resistor to set the poweron threshold, avoid using a pull-up resistor that is too small to increase the operational quiescent current. www.MonolithicPower.com MPS Proprietary Information.

When the silicon die temperature exceeds 175°C, the entire chip shuts down, and EN reports a fail mode. When the temperature drops below its lower threshold (typically 125°C), the chip is enable again after a 700ms delay, typically.

The current limit is a function of the external current limit resistor. Table 1 and Figure 3 list examples of typical current limit values as a function of the resistor value.

Min. VCC - 0.2V VMODE_HIGH VMODE_LOW Max. 0.2V The OVP threshold can also be set by connecting a resistor from MODE to ground. In this case, the OVP clamp threshold is given by Equation (3): Vclamp (V) 0.047 RMODE (KΩ） 0.3(V) (3) RMODE should be above 68kΩ. For example, an RMODE value of 76.8kΩ can set the OVP clamp threshold to 3.9V. When RMODE is used, place a 39pF capacitor from MODE to GND. Setting the Soft-Start Time The soft-start time is related to the dV/dt slew rate and input voltage and can be calculated with Equation (4): t_ss(ms) Vin(V) dv/dt (V/ms) (4) The dV/dt slew rate is controlled by the external DV/DT capacitor setting and MODE setting. Table 3 shows the dV/dt slew rate value when DV/DT is floating. Figure 3: Current Limit vs. Current Limit Resistor The MP5016H current limit can be programmed from 0.7A to 5A by connecting the correct resistor (RLIMIT). The current limit cannot be set too low, because the MP5016H works in sleep mode when the load is lower than 0.38A, typically. The current limit logic is disabled in sleep mode, also. Setting the Over-Voltage Clamp Threshold Drive MODE high to VCC to set the output OVP clamp voltage at 15.2V. Drive MODE low to GND to set the output OVP clamp voltage at 5.75V.
