ON is an asserted HIGH, level-sensitive CMOS input with ON_VIL < 0.3 V and ON_VIH > 0.9 V. As the ON pin input circuit does not have an internal pull-down resistor, connect this pin to a general-purpose output (GPO) of a microcontroller, an application processor, or a system controller, do not allow this pin to be open-circuited. 2 SEL0 Input As level-sensitive, CMOS inputs with VIL < 0.3 V and VIH > 1.65 V, the SEL0 (LSB) and the SEL1 (MSB) pins select one of four VIN overvoltage lockout thresholds. Please see the Applications Section for additional information and the Electrical Characteristics table for the VIN overvoltage thresholds. A logic LOW on either pin is achieved by connecting the pin of interest to GND; a logic HIGH on either pin is achieved by connecting a 10 kΩ external resistor from the pin in question to the system’s local logic supply. 3 GND GND Pin 3 is the main ground connection for the SLG59H1128V’s internal charge pump, its gate driver and current-limit circuits as well as its internal state machine. Therefore, use a short, stout connection from Pin 3 to the system’s analog or power plane. 4-8 VIN VIN supplies the power for the operation of the SLG59H1128V, its internal control circuitry, and the drain terminal of the nFET load switch. With 5 pins fused together at VIN, connect a 47 μF (or MOSFET larger) low-ESR capacitor from this pin to ground. Capacitors used at VIN should be rated at 50 V or higher. 9-13 VOUT Source terminal of n-channel MOSFET (5 pins fused for VOUT). Connect a 22 μF (or larger) MOSFET low-ESR capacitor from this pin to ground. Capacitors used at VOUT should be rated at 50 V or higher. 14 SEL1 15 16 FAULT CAP Input Please see SEL0 Pin Description above Output An open drain output, FAULT is asserted within TFAULTLOW when a VIN overvoltage, a current-limit, or an over-temperature condition is detected. FAULT is deasserted within TFAULTHIGH when the fault condition is removed. Connect an 100 kΩ external resistor from the FAULT pin to local system logic supply. Output A low-ESR, stable dielectric, ceramic surface-mount capacitor connected from CAP pin to GND sets the VOUT slew rate and overall turn-on time of the SLG59H1128V. For best performance, the range for CSLEW values are 10 nF ≤ CSLEW ≤ 20 nF – please see typical characteristics for additional information. Capacitors used at the CAP pin should be rated at 10 V or higher. Please consult Applications Section on how to select CSLEW based on VOUT slew rate and loading conditions. IOUT is the SLG59H1128V’s power MOSFET load current monitor output. As an analog current output, this signal when applied to a ground-reference resistor generates a voltage proportional to the current through the n-channel MOSFET. The IOUT transfer characteristic is typically 10 μA/A with a voltage compliance range of 0.5 V ≤ VIOUT ≤ 4 V. Optimal IOUT linearity is exhibited for 0.5 A ≤ IDS ≤ 5 A. In addition, it is recommended to bypass the IOUT pin to GND with a 0.18 nF capacitor. 17 IOUT Output 18 RSET Input A 1%-tolerance, metal-film resistor between 18 kΩ and 91 kΩ sets the SLG59H1128V’s active current limit. A 91 kΩ resistor sets the SLG59H1128V’s active current limit to 1 A and a 18 kΩ resistor sets the active current limit to 5 A.

One particular protection feature is their Safe Operation Area (SOA) protection. SOA protection is automatically activated under overpower and, in some cases, under overcurrent conditions. Overpower SOA is activated if package power dissipation exceeds an internal 10 W threshold and High Voltage GreenFET devices will quickly switch off (open circuit) upon overpower detection and automatically resume (close) nominal operation once overpower condition no longer exists. One of the possible ways to have an overpower condition trigger SOA protection is when High Voltage GreenFET products are enabled into heavy output resistive loads and/or into large load capacitors. It is under these conditions to follow carefully the “Safe Start-up Loading” guidance in the Applications section of the datasheet. During an overcurrent condition, High Voltage GreenFET devices will try to limit the output current to the level set by the external RSET resistor. Limiting the output current, however, causes an increased voltage drop across the FET’s channel because the FET’s RDSON increased as well. Since the FET’s RDSON is larger, package power dissipation also increases. If the resultant increase in package power dissipation is higher/equal than 10 W, internal SOA protection will be triggered and the FET will open circuit (switch off). Every time SOA protection is triggered, all High Voltage GreenFET devices will automatically attempt to resume nominal operation after 160 ms. The automatic retry attempt only allows power-up with SOA at 5 W. This SOA fold back power ensures that the FET survives a short circuit condition. To clear the 5 W SOA fold back, switch the ON pin to “LOW” to power reset SOA to 10 W. Safe Start-up Condition SLG59H1128V 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 VOUT ramping (Figure 15) or repeated restarts (Figure 13 and Figure 14). In general, under light loading on VOUT, VOUT ramping can be controlled with CSLEW value. The following equation serves as a guide: CSLEW = TRISE 20 x 4.9 µA x VIN 3 where TRISE = Total rise time from 10% VOUT to 90% VOUT VIN = Input Voltage CSLEW = Capacitor value for CAP pin When capacitor and resistor loading on VOUT during start up, the following tables will ensure VOUT ramping is monotonic without triggering internal protection: Safe Start-up Loading for VIN = 12 V (Monotonic Ramp) Slew Rate (V/ms) CSLEW (nF)2 CLOAD (µF) RLOAD (Ω) 1 33.3 500 7 2 16.7 250 7 3 11.1 160 7 4 8.3 120 7 5 6.7 100 7 Datasheet CFR0011-120-01 Revision 1.03 Page 25 of 35 2-Feb-2022 ©2022 Renesas Electronics Corporation  SLG59H1128V A 22 V, 13.1 mΩ, 5 A Load Switch with VIN Lockout Select and MOSFET Current Monitor Output Safe Start-up Loading for VIN = 20 V (Monotonic Ramp) Slew Rate (V/ms) CSLEW (nF)2 CLOAD (µF) RLOAD (Ω) 0.5 66.7 500 25 1.0 33.3 250 25 1.5 22.2 160 25 2.0 16.7 120 25 2.5 13.3 100 25 Note 2: Select the closest-value tolerance capacitor.

SEL1 SEL0 VIN(OVLO) (Typ) 0 0 6V 0 1 10.8 V 1 0 14.4 V 1 1 24 V For example, SEL[1,1] would be the most appropriate setting for applications where the steady-state VIN can extend up to 20 V without causing any damage to the SLG59H1128V since the IC is 29-V tolerant. With an activated SLG59H1128V (ON=HIGH) and at any time VIN crosses the programmed VIN overvoltage threshold, the state machine opens the load switch and asserts the FAULT pin within TFAULTLOW. In applications with a deactivated or inactive SLG59H1128V (VIN > VIN(UVLO) and ON=LOW) and if the applied VIN is higher than the programmed VIN(OVLO) threshold, the SLG59H1128V’s state machine will keep the load switch open circuited if the ON pin is toggled LOW-to-HIGH. In these cases, the FAULT pin will also be asserted within TFAULTLOW and will remain asserted until VIN resumes nominal, steady-state operation. In all cases, the SLG59H1128V’s VIN undervoltage lockout threshold is fixed at VIN(UVLO).

The primary contributor to the increase in the junction temperature of the SLG59H1128V is the power dissipation of its power MOSFET. Its power dissipation and the junction temperature in nominal operating mode can be calculated using the following equations: PD = RDSON x IDS2 where: PD = Power dissipation, in Watts (W) RDSON = Power MOSFET ON resistance, in Ohms (Ω) IDS = Output current, in Amps (A) and TJ = PD x θJA + TA where: TJ = Junction temperature, in Celsius degrees (°C) θJA = Package thermal resistance, in Celsius degrees per Watt (°C/W) TA = Ambient temperature, in Celsius degrees (°C) In current-limit mode, the SLG59H1128V’s power dissipation can be calculated by taking into account the voltage drop across the load switch (VIN-VOUT) and the magnitude of the output current in current-limit mode (IACL): PD = (VIN-VOUT) x IACL or PD = (VIN – (RLOAD x IACL)) x IACL where: PD = Power dissipation, in Watts (W) VIN = Input Voltage, in Volts (V) RLOAD = Load Resistance, in Ohms (Ω) IACL = Output limited current, in Amps (A) VOUT = RLOAD x IACL Datasheet CFR0011-120-01 Revision 1.03 Page 27 of 35 2-Feb-2022 ©2022 Renesas Electronics Corporation  SLG59H1128V A 22 V, 13.1 mΩ, 5 A Load Switch with VIN Lockout Select and MOSFET Current Monitor Output Layout Guidelines: 1. Since the VIN and VOUT pins dissipate most of the heat generated during high-load current operation, it is highly recommended to make power traces as short, direct, and wide as possible. A good practice is to make power traces with absolute minimum widths of 15 mils (0.381 mm) per Ampere. A representative layout, shown in Figure 24, illustrates proper techniques for heat to transfer as efficiently as possible out of the device; 2. To minimize the effects of parasitic trace inductance on normal operation, it is recommended to connect input CIN and output CLOAD low-ESR capacitors as close as possible to the SLG59H1128V's VIN and VOUT pins; 3. The GND pin should be connected to system analog or power ground plane. 4. 2 oz. copper is recommended for high current operation. SLG59H1128V Evaluation Board: А High Voltage GreenFET Evaluation Board for SLG59H1128V is designed according to the statements above and is illustrated on Figure 24. Please note that evaluation board has D_Sense and S_Sense pads. They cannot carry high currents and dedicated only for RDSON evaluation. Figure 24.
