Product details

Overview

STSPIN240 from STMicroelectronics is a dual brush DC motor driver IC integrating two fully protected full-bridge power stages and independent PWM current controllers in a VFQFPN 3×3×1.0 mm, 16-pin package. It operates from 1.8–10 V, delivers up to 1.3 Arms per bridge, features 0.4 Ω typical R_DS(ON) (HS+LS), and supports adjustable off-time current regulation - enabling precise torque control in compact battery-powered motion systems.

For engineers reviewing the STSPIN240 datasheet, STSPIN240 pinout, STSPIN240 application, or STSPIN240 equivalent, this device is selected for low-voltage dual-motor control where standby current <80 nA, non-dissipative overcurrent protection, thermal shutdown at 160 °C, and integrated sense-based current limiting are critical design requirements.

Technical Context

The STSPIN240 implements two independent PWM current controllers, each comparing sensed voltage (V_SENSEA/V_SENSEB) against an external reference (V_REF = 0.1–0.5 V) to trigger fixed-off-time decay. The internal oscillator frequency is set by an external resistor on TOFF (10–150 µs off-time range), with ±20% precision and 2% jitter.

Each full-bridge supports four-phase operation via PHx/PWMx inputs, enabling forward/reverse/brake/coast states; EN\FAULT serves as both enable input and open-drain fault indicator (V_RELEASE = 0.4 V), while STBY\RESET forces zero-consumption mode with 10–80 nA supply current.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	1.8–10 V - enables direct Li-ion (3.7 V), Ni-MH (1.2×2–4), or alkaline (1.5×2–4) battery operation without LDO pre-regulation.
Max output current	1.3 Arms per bridge - supports continuous drive of small DC motors up to ~3 W mechanical output at 5 V.
R_DS(ON) (HS+LS)	0.4 Ω typ. at 10 V / 1.3 A - minimizes conduction loss and self-heating in space-constrained portable designs.
Standby current	<80 nA - extends battery life in intermittently active devices (e.g., toothbrushes, POS printers) by eliminating quiescent drain.
Overcurrent threshold	2 A - provides non-dissipative, cycle-by-cycle current limiting that disables outputs and asserts EN\FAULT without external sensing components.
Thermal shutdown	160 °C with 40 °C hysteresis - prevents latch-up during sustained overload or poor PCB thermal layout.
ESD rating	HBM: 2 kV, CDM: 500 V - ensures robustness during manual handling and board assembly in high-volume consumer manufacturing.

Pinout & Package

VFQFPN 3×3×1.0 mm, 16-pin package with exposed thermal pad (EPAD) requiring solder connection to GND for optimal thermal performance (R_thJCbot = 9.1 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
PHA / PHB	Phase control input (Bridge A/B)	Determines motor direction: logic high enables forward drive (OUTx1→OUTx2), low enables reverse (OUTx2→OUTx1) when PWM is active.
PWMA / PWMB	PWM enable input (Bridge A/B)	Controls switching duty cycle; rising/falling edges trigger ON/OFF transitions with 125 ns propagation delay.
OUTA1/OUTA2/OUTB1/OUTB2	Power bridge outputs	Drive motor terminals directly; each pair forms a full H-bridge capable of bidirectional current flow up to 1.3 Arms.
SENSEA / SENSEB	Current sense feedback	Connects to low-side sense resistors (e.g., 330 mΩ); voltage drop compared to REF sets peak current limit per bridge.
REF	Analog reference input	Sets current limit threshold: V_REF = R_SNS × I_LOAD,peak; 0.1–0.5 V range balances noise immunity and resolution.
TOFF	Oscillator timing input	External resistor to GND sets OFF time (10–150 µs); determines current decay duration and effective PWM frequency.
EN\FAULT	Enable input / Open-drain fault output	Low = power stage disabled; fault events (OCP, OVP, TSD) pull this pin low to signal MCU and hold disable until V<sub>RELEASE</sub> crossed.
STBY\RESET	Standby control input	Logic low forces zero-consumption state: all circuitry powered down except wake-up comparators; V_STBYL = 0.9 V, V_STBYH = 1.48 V.

Key Features

Feature	Design Value
Adjustable PWM current control	Independent per-bridge regulation using external REF and TOFF resistors - eliminates need for external current-sense amplifiers or microcontroller-based closed-loop control.
Non-dissipative overcurrent protection	Detects overcurrent via sense pins and disables outputs within nanoseconds without shunt resistor heating - preserves efficiency and reliability in intermittent-load applications.
Ultra-low standby consumption	<80 nA supply current in STBY mode - reduces annual battery drain to sub-microampere-hours, critical for multi-year shelf-life medical and wellness devices.
Integrated thermal shutdown	160 °C trip point with 40 °C hysteresis - prevents permanent damage during blocked-rotor conditions or inadequate heatsinking in sealed enclosures.
Robust fault signaling	Open-drain EN\FAULT pin drives external capacitor network (C_EN/R_EN) to set programmable fault recovery delay (10–100 µs) - simplifies MCU fault-handling logic.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual brush DC motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TB6612FNG	Higher supply range (2.7–13.5 V), higher R_DS(ON) (0.56 Ω typ.), no standby mode (<1 μA), fixed 10 μs off-time.	Lacks ultra-low standby current and adjustable off-time - less suitable for multi-year battery life or fine-tuned current ripple control.	Prefer when wider input voltage tolerance is needed and standby current is not critical.
DRV8837	Single-channel, lower max current (1.8 A peak), no integrated current sense comparator, requires external current sense amp and reference.	Requires additional BOM components for current regulation; not pin-compatible for dual-motor use without duplication.	Choose only for single-motor systems where cost-per-channel is prioritized over integration and footprint.

Compared with TB6612FNG and DRV8837, the STSPIN240 uniquely combines dual-channel integration, sub-80 nA standby, adjustable off-time current control, and non-dissipative OCP - making it the only option qualified for long-life, low-noise, dual-motor battery applications demanding minimal external components.

FAQ

What is the minimum supply voltage required for STSPIN240 to operate correctly?

The STSPIN240 has a guaranteed operational range from 1.8 V to 10 V. Below 1.8 V, the internal regulators and comparators may not function reliably; VS turn-on threshold is 1.45–1.79 V (hysteresis 180 mV), so stable startup requires ≥1.8 V under load. At 1.8 V, R_DS(ON) increases to ~0.53 Ω, reducing available torque but maintaining functionality.

How does the STSPIN240 implement non-dissipative overcurrent protection?

It monitors voltage across the external sense resistors (SENSEA/SENSEB) and compares it to V_REF. When sensed voltage exceeds V_REF, the current limiter triggers, initiating fixed off-time decay and disabling the power stage if current remains above threshold. No external shunt heating occurs because protection activates before significant energy dissipation in the sense resistor.

Can STSPIN240 drive stepper motors?

No - the STSPIN240 is designed exclusively for brushed DC motors. Its truth table and control logic (PHA/PWMA) support only full-bridge bidirectional drive of two independent DC motors. Stepper motor control requires phase sequencing, microstepping, and current waveform shaping not implemented in this device.

What is the recommended PCB layout practice for thermal management?

Connect the exposed pad (EPAD, Pin 16) directly to a large copper pour tied to GND with ≥4 thermal vias (300 µm diameter) beneath it. Use a 21.2×21.2 mm 2s2p 1 oz copper board per JEDEC JESD51-8; this achieves R_thJB = 23.3 °C/W. Avoid isolating the EPAD - doing so raises junction temperature by >40 °C at 1.3 A continuous load.
