Product details
Overview
DRV110PWR from Texas Instruments is a PWM current controller IC designed to drive external N-channel MOSFETs for solenoid, relay, and valve actuation. It supports 120/230 V AC (via rectifier + RS) or 6–48 V DC input, regulates peak current up to 330 mA (RSENSE = 1 Ω), holds current at 65 mA, and operates with programmable keep time (100 ms @ CKEEP = 1 µF), PWM frequency (15–27 kHz), and thermal shutdown at 160°C. Used in industrial pneumatic valves and contactor drivers.
For engineers reviewing the DRV110PWR datasheet, DRV110PWR pinout, DRV110PWR application, or DRV110PWR equivalent, key selection criteria include its dual-voltage supply capability (AC line-derived or DC), external resistor-programmable IPEAK/IHOLD, integrated Zener-clamped VIN regulation, and TSSOP-14 package compatibility with high-temperature ambient operation (–40°C to +125°C).
Technical Context
The DRV110PWR implements a cycle-by-cycle hysteresis-based current control loop: SENSE voltage is compared against programmable VPEAK/VHOLD references, and OUT drives the external MOSFET gate with variable duty cycle (7.5–100%) to regulate solenoid current. Its internal 15-V Zener clamps VIN when powered from rectified AC or high DC rails, requiring only an external RS current-limiting resistor and CIN bypass capacitor.
Three operational states are sequenced by EN: OFF (OUT disabled), PEAK (ramp-to-IPEAK and hold for tKEEP), and HOLD (regulate at IHOLD). The 14-pin TSSOP package exposes HOLD, STATUS, and all configuration pins (PEAK, HOLD, OSC, KEEP), enabling full external tuning of timing and current thresholds - unlike the 8-pin variant where HOLD is unconnected and defaults internally.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 6–330 V (clamped to ~11–15 V by internal Zener; enables direct 120/230 V AC operation via rectifier + RS) |
| IPEAK (typ) | 300 mA (with RSENSE = 1 Ω, PEAK = GND; externally adjustable from 270–330 mA via RPEAK) |
| IHOLD (max) | 65 mA (with RSENSE = 1 Ω, HOLD = GND; 14-pin package only; sets low-power holding state) |
| tKEEP | 100 ms (programmed by CKEEP = 1 µF; defines duration of peak current before transition to hold mode) |
| fPWM | 15–27 kHz (default 20 kHz; set by ROSC = 160 kΩ; determines switching frequency and EMI profile) |
| Thermal Shutdown | 160°C (junction temperature; disables OUT and pulls STATUS high-Z; recovers at 140°C) |
| UVLO Threshold | 4.6 V (VIN undervoltage lockout prevents erratic operation during brownout or startup) |
Pinout & Package
DRV110PWR is supplied in a 14-pin TSSOP (PW) package, 5.00 mm × 4.40 mm body size, with exposed thermal pad (not electrically connected). Pin 12 is STATUS (open-drain output); pins 1, 2, 3, 4, 5, 9, 11, 13, and 14 are active; pins 6, 10 are NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (13) | Enable input | Active-high logic control; internal pullup allows self-enable on power-up; disables OUT and STATUS when low |
| PEAK (3) | Peak current reference setting | Connects to external RPEAK to set VPEAK (300–900 mV), determining IPEAK = VPEAK / RSENSE |
| HOLD (4) | Hold current reference setting | Connects to external RHOLD to set VHOLD (50–150 mV); only available in 14-pin package; sets IHOLD = VHOLD / RSENSE |
| KEEP (2) | Keep time timing input | Sources constant current into CKEEP; time to 100 mV threshold defines tKEEP (e.g., 100 ms @ 1 µF) |
| OSC (5) | PWM clock frequency setting | Connects to ROSC to ground; sets fPWM from 15–27 kHz (ROSC = 160–200 kΩ) |
| SENSE (9) | Current sense input | Monitors voltage across RSENSE; compared against VPEAK/VHOLD to control OUT duty cycle |
| OUT (11) | MOSFET gate driver output | Push-pull capable (±15 mA); drives external N-MOSFET gate; high = VIN, low = GND |
| STATUS (12) | Status indicator output | Open-drain; pulled low during normal operation; high-Z during UVLO or thermal shutdown |
| VIN (7) | Supply input | Input for 6–330 V source; internally clamped by Zener diode; requires RS current limiter for >15 V inputs |
| GND (8) | Ground reference | Power and signal return; connects to system ground and RSENSE low-side |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Zener supply clamp | Enables direct 120/230 V AC operation using rectifier + RS resistor; eliminates need for external LDO or buck converter |
| Programmable peak-to-hold current transition | Reduces solenoid power dissipation by 60–80% after activation - e.g., 300 mA → 50 mA - without mechanical redesign |
| External timing and current tuning | All critical parameters (tKEEP, IPEAK, IHOLD, fPWM) set via passive components - no firmware or calibration required |
| Robust protection suite | Includes undervoltage lockout (4.6 V), thermal shutdown (160°C), and automatic recovery (140°C hysteresis) |
| High-temp rated package | TSSOP-14 rated for –40°C to +125°C ambient; RθJA = 122.6°C/W enables convection-cooled designs in enclosed industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar solenoid current control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TBD7200A | Integrated high-side driver (no external MOSFET required); fixed 1 A peak/300 mA hold; no AC-line input support | Lower component count but limited to ≤28 V DC; cannot replace DRV110PWR in 120/230 V AC systems | Select TBD7200A only for low-voltage DC-only solenoid applications where board space is constrained and external FET is undesirable. |
| TPS27082 | Smart high-side load switch (not current-regulating); 2.7–18 V input; no peak/hold sequencing or timing control | Provides ON/OFF control only; lacks current regulation, tKEEP, IPEAK/IHOLD tuning, and AC-line capability | Choose TPS27082 only for simple on/off solenoid switching where precise current waveform control is unnecessary. |
Compared with TBD7200A and TPS27082, DRV110PWR uniquely supports direct 120/230 V AC input, fully programmable peak/hold current and timing, and external MOSFET flexibility - making it the only option for high-voltage, thermally optimized, and field-tunable solenoid drivers.

FAQ
What input voltage ranges does the DRV110PWR support?
The DRV110PWR supports 6–330 V input at VIN, enabled by its internal Zener diode that clamps voltage to ~11–15 V depending on temperature and EN state. This allows direct connection to rectified 120 VAC or 230 VAC mains (using RS current-limiting resistor) or standard 24 VDC/48 VDC supplies. Operation below 6 V is prohibited due to UVLO activation at 4.6 V.
How is peak and hold current configured on the DRV110PWR?
Peak current (IPEAK) is set by connecting RPEAK between PEAK (pin 3) and GND, generating VPEAK (300–900 mV) referenced against RSENSE to yield IPEAK = VPEAK / RSENSE. Hold current (IHOLD) uses the same method on HOLD (pin 4), producing VHOLD (50–150 mV) and IHOLD = VHOLD / RSENSE. Both are fully independent and require RSENSE = 1 Ω for nominal values shown in the datasheet.
Does the DRV110PWR require an external MOSFET, and what type is recommended?
Yes, the DRV110PWR requires an external N-channel MOSFET connected between the solenoid and ground, with its gate driven by OUT (pin 11). TI recommends logic-level or standard-threshold N-MOSFETs rated ≥20 V VDS and ≥2 A ID, such as CSD18532Q5B or Si2302DS, to ensure full enhancement at VIN = 14 V and handle peak gate charge at 20 kHz PWM.
What is the function of the STATUS pin on the DRV110PWR?
The STATUS pin (pin 12) is an open-drain output that is actively pulled low during normal operation (EN high, no UVLO or thermal fault). It goes high-impedance (Hi-Z) if undervoltage lockout triggers (VIN < 4.6 V) or thermal shutdown activates (TJ > 160°C), allowing microcontroller monitoring with a single pullup resistor - no additional level-shifting or buffering needed for fault detection.
Can the DRV110PWR operate without external timing components?
Yes, the DRV110PWR can operate with default settings: connect PEAK and HOLD to GND for nominal IPEAK = 300 mA / IHOLD = 50 mA (RSENSE = 1 Ω), tie OSC to GND for fPWM ≈ 20 kHz, and omit CKEEP for tKEEP = 0 (immediate transition to hold mode). However, CKEEP is required for any non-zero keep time, and RS + CIN remain mandatory for AC-line operation.
