The device is designed to regulate the current with a well-controlled waveform to guarantee activation and to reduce power dissipation at the same time. The solenoid current is ramped up fast to ensure opening of the valve or relay. After the initial ramping, solenoid current is kept at peak value to ensure the correct operation, after which it is reduced to a lower hold level in order to avoid thermal problems and reduce power dissipation. 1 • • • • • • • Integrated MOSFET With PWM to Control Solenoid Current – Integrated Sense Resistor for Regulating Solenoid Current Fast Ramp-Up of Solenoid Current to Guarantee Activation Solenoid Current is Reduced in Hold Mode for Lower Power and Thermal Dissipation Peak Current, Keep Time at Peak Current, Hold Current, and PWM Clock Frequency Can Be Set Externally.

The device provides a quick ramp to a high peak current value in order to ensure opening of the valve or relay. The peak current is held for a programmable time and then released to a lower value to maintain the open state of the valve or relay while reducing the total current consumption. Peak current duration, peak current amount, hold current amount (in the 14-pin package), and PWM frequency can all be controlled by external components or used at default levels by omitting these components (except peak current duration). Enable and disable of the switch is controlled by the EN pin which has an internal pullup to VIN. The DRV120 also features a wide VIN range from 6 V to 28 V. Finally, the 14-pin package features an open-drain pulldown path on the STATUS pin which is enabled as long as undervoltage lockout or thermal shutdown has not triggered. 7.2 Functional Block Diagram ROSC <STATUS> OSC 1 VS VS VIN LDO UVLO Thermal Shutdown OSC LS 500 kW EN D1 OUT PWMCLK 1 uA PWM Control VREF GND MUX VHOLD 1 <RHOLD> RPEAK CKEEP 1 KEEP PEAK <HOLD> 1 VPEAK REF RSENSE 75 mV Available only in the 14-pin package 7.3 Feature Description The DRV120 controls the current through the solenoid as shown in Figure 2. Activation starts when EN pin voltage is pulled high either by an external driver or internal pullup. In the beginning of activation, DRV120 allows the load current to ramp up to the peak value IPEAK and it regulates it at the peak value for the time, tKEEP, before reducing it to IHOLD. The load current is regulated at the hold value as long as the EN pin is kept high. The initial current ramp-up time depends on the inductance and resistance of the solenoid. Once EN pin is driven to GND, DRV120 allows the solenoid current to decay to zero.

Typical Current Waveform Through the Solenoid tKEEP is set externally by connecting a capacitor to the KEEP pin. A constant current is sourced from the KEEP pin that is driven into an external capacitor resulting in a linear voltage ramp. When the KEEP pin voltage reaches 75 mV, the current regulation reference voltage, VREF, is switched from VPEAK to VHOLD. Dependency of tKEEP from the external capacitor size can be calculated by: ésù tKEEP ëés ûù = CKEEP ëéF ûù × 75 × 103 ê ú ëF û (1) The current control loop regulates, cycle-by-cycle, the solenoid current by using an internal current-sensing resistor and MOSFET switch. During the ON-cycle, current flows from OUT pin to GND pin through the internal switch as long as voltage across the current-sensing resistor is less than VREF. As soon as the current sensing voltage is above VREF, the internal switch is immediately turned off until the next ON-cycle is triggered by the internal PWM clock signal. In the beginning of each ON-cycle, the internal switch is turned on and stays on for at least the time determined by the minimum PWM signal duty cycle, DMIN. IPEAK and IHOLD depend on fixed resistance values RPEAK and RHOLD approximately as shown in Figure 3. If the PEAK pin is connected to ground or if RPEAK or RHOLD is below 33.33 kΩ (typical value), then IPEAK is at its default value (internal setting) of 200 mA for IPEAK and 50 mA for IHOLD. The IPEAK value can alternatively be set by connecting an external resistor to ground from the PEAK pin. For example, if a 50-kΩ (= RPEAK) resistor is connected between PEAK and GND, then the externally set IPEAK level will be 250 mA. If RPEAK = 200 kΩ is, then the externally set IPEAK level will be 83 mA. In the 8-pin package, IHOLD is set to 50 mA by default. In the 14-pin package, external settings of IHOLD works in the same way as IPEAK. External settings for IPEAK and IHOLD are independent of each other. Approximate IPEAK and IHOLD values can be calculated by using Equation 2 and Equation 3. 250mA IPEAK = × 66.67kW ;66.67kW < RPEAK < 550kW RPEAK (2) I 8 HOLD = 100mA × 66.67kW ;66.67kW < RHOLD < 250kW RHOLD Submit Documentation Feedback (3) Copyright © 2012–2015, Texas Instruments Incorporated Product Folder Links: DRV120 DRV120 www.ti.com SLVSBG3B – JUNE 2012 – REVISED JULY 2015 Feature Description (continued) Figure 3. PEAK and HOLD Mode Current Settings Frequency of the internal PWM clock signal, PWMCLK, that triggers each ON-cycle can be adjusted by external resistor, ROSC, connected between OSC and GND. Frequency as a function of resistor value is shown in Figure 4. Default frequency is used when OSC is connected to GND directly. PWM frequency as a function of external fixed adjustment resistor value (greater than 66.67 kΩ) is given in Equation 4. 60kHz fPWM = × 66.67kW ;66.67kW < ROSC < 2MW ROSC (4) Figure 4. PWM Clock Frequency Setting Open-drain STATUS output is deactivated if either undervoltage lockout or thermal shutdown blocks have triggered. 7.4 Device Functional Modes The DRV120 transitions through three different states. The first is the OFF state, where the EN pin is low and the PWM output is off. The second is the PEAK state, which begins when the EN pin is pulled high by an external controller or internal pullup, and ends once tKEEP has been reached. During this state, the PWM operates in order to reach the IPEAK set by the RPEAK. Finally, once tKEEP has been reached, the PWM continues to operate, but at the IHOLD level. This continues until the EN pin is forced low again and the PWM turns off.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The DRV120 device is designed to operate a solenoid valve or relay. A typical DC input design will be outlined in Typical Application. Approximate resistor and capacitor values for the peak current, hold current, and keep time will be derived for a sample application. 8.2 Typical Application VS LS 1 <STATUS> D1 VIN VS OUT DRV120 VEN EN 1 GND KEEP CKEEP <RHOLD> RPEAK 1 PEAK OSC <HOLD> 1 ROSC Available only in the 14-pin package Figure 5. Default Configuration 8.2.1 Design Requirements The key elements to identify here are the system input voltage, peak current, hold current, and peak keep time values required for the solenoid or relay being used. With these values, approximate RS, RPEAK, RHOLD (for 14-pin package), and CKEEP values can be determined and the proper FET and diode can be identified. ROSC can be varied in order to tune the circuit to the chosen solenoid or relay. 8.2.2 Detailed Design Procedure First, with the known peak current, hold current, and peak keep time values known, the RPEAK, RHOLD (for 14-pin package), and CKEEP values can be determined. Calculation will proceed based on example values shown in Table 1. 10 Submit Documentation Feedback Copyright © 2012–2015, Texas Instruments Incorporated Product Folder Links: DRV120 DRV120 www.ti.com SLVSBG3B – JUNE 2012 – REVISED JULY 2015 Table 1. Sample Application Values VARIABLE VALUE Peak current 150 mA Hold current 50 mA Keep time 100 ms RPEAK and RHOLD (if applicable) can be determined using Equation 2 and Equation 3. For the sample values, RPEAK is set to 111 kΩ and RHOLD can be shorted to GND. TI recommends that a 0-Ω resistor is used for prototyping in case changes to this value are desired. Next, CKEEP can be set based on Equation 1, 1.33 µF for the sample values. ROSC can initially be shorted to GND, but again a 0-Ω resistor is recommended for prototyping. Additionally, a filter on the SENSE line may be added if it will be in a high-noise environment and is recommended for prototyping. Typical values for this are 1 kΩ and 100 pF. Finally, a current recirculation diode must be chosen based on the current values defined in Table 1. The current recirculation diode should be a fast recovery diode. 8.2.3 Application Curves Lind = 1 H Rind = 50 Ω Figure 6.

An input capacitor of 4.7 µF (typical) is required as well. Current requirements will be set by the required current from the solenoid. 10 Layout 10.1 Layout Guidelines The trace for the solenoid or relay current should be wide in order to prevent any unexpected voltage drop. Diode placement should not be far from the inductor and both should be placed close to the output. 10.2 Layout Example Figure 7.

Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
