8-SOIC low-side driver with internal PWM
The DRV103U/2K5: It integrates a PWM oscillator and a status flag output, so you get pulse-width modulation and fault indication without an external timer or microcontroller pin. Rated for a load supply from 8 V to 32 V and a continuous output current up to 1.5 A, this part suits 12 V and 24 V industrial and automotive solenoid drivers where the load current stays under that ceiling. The internal current-limiting and over-temperature protection mean the driver folds back or shuts down before the copper traces or the solenoid coil let the magic smoke out.
The 1.5 A maximum output current is the continuous rating at the N-channel FET's on-resistance and the 8-SOIC's thermal impedance — a solenoid that pulls 1.2 A steady-state leaves headroom for inrush without hitting the current-limit threshold. The internal PWM oscillator generates a fixed-frequency drive signal — you enable it with a logic-level On/Off input (non-inverting), and the driver toggles the load at the internal rate. The Status Flag output pulls low when the driver hits current limit or an over-temperature event, so a downstream microcontroller or PLC input can latch the fault and sequence a retry or a safe shutdown. The N-channel low-side topology means the load connects between the positive supply and the driver's drain — the load sees the full supply voltage when the driver is on, and the driver's drain is pulled to ground through the internal FET.
Active production and compliance
The 8-SOIC footprint is widely supported in hobbyist and production PCB layouts — the 0.154-inch (3.90 mm) body width fits a standard SOIC-8 land pattern.
