Product details

Overview

E-L6202 from STMicroelectronics is a monolithic full-bridge DMOS motor driver in Multipower-BCD technology, designed for bidirectional DC and bipolar stepper motor control. It delivers up to 5 A peak output current, supports 48 V supply voltage, features 0.3 Ω typical R_DS(ON), integrated cross-conduction protection, and operates up to 100 kHz switching frequency in industrial motor drive systems.

For engineers reviewing the E-L6202 datasheet, E-L6202 pinout, E-L6202 application, or E-L6202 equivalent, this page provides verified pin functions, thermal shutdown behavior, bootstrap capacitor requirements, RMS current capability (1.5 A), and TTL/CMOS/µC-compatible logic interface details essential for H-bridge layout and current-sense design.

Technical Context

The L6202 integrates two independent half-bridges with N-channel DMOS high-side and low-side transistors, each driven by separate IN1/IN2 inputs and jointly enabled via a single EN pin. Its internal charge pump and bootstrap circuitry (BOOT1/BOOT2) ensures ≥10 V gate drive for high-side MOSFETs without external high-voltage drivers.

It implements fixed dead time (>40 ns) to prevent shoot-through, includes internal thermal shutdown at 150 °C, and uses an internal 13.5 V reference (Vref) with 2 mA sink capability for current-sense amplifier biasing - all operating within a 12–48 V supply range and supporting synchronous rectification via intrinsic body diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage (Vs)	12–48 V - defines usable rail range for motor power stage; 42 V typical max for continuous operation
Peak Output Current	5 A - supports short-duration torque bursts in DC motor startup or stepper microstepping
RMS Current Rating	1.5 A - determines sustained thermal load limit for L6202 in Powerdip18 package
R_DS(ON) (typ.)	0.3 Ω @ 25 °C - sets conduction loss: P_ON = 0.3 × I_RMS² ≈ 0.675 W at full rated RMS current
Switching Frequency	Up to 100 kHz - enables high-resolution PWM speed control while staying within safe SOA limits
Thermal Shutdown	150 °C junction - autonomous disable/recovery cycle prevents irreversible silicon damage under overload
Vref Output	13.5 V @ 2 mA - supplies stable bias for external current-sense amplifiers (e.g., L6506)

Pinout & Package

Package: Powerdip18 (12+3+3 pin configuration, through-hole, 24.8 mm × 8.8 mm footprint, 3.3 mm height).

Pin/Terminal	Circuit Role	Design Meaning
1	SENSE	Current-sense feedback node; connects to Rsense resistor for closed-loop motor current regulation
2	ENABLE	Global enable input; logic high activates both half-bridges; low disables all outputs
3, 4, 5, 6, 13, 14, 15	GND	Multiple ground terminals - reduce ground bounce and improve thermal dissipation in Powerdip18
7	OUT2	Output of second half-bridge - drives one motor terminal in H-bridge topology
8	Vs	Main motor supply input - feeds both high-side and low-side DMOS stages
9	OUT1	Output of first half-bridge - drives opposite motor terminal; forms diagonal pair with OUT2
10	BOOT1	Bootstrap capacitor node for high-side gate drive of first half-bridge; requires ≥10 nF ceramic cap
11	IN1	Digital control input for first half-bridge; TTL/CMOS/µC compatible; controls OUT1 sourcing/sinking
12	BOOT2	Bootstrap capacitor node for high-side gate drive of second half-bridge
16	IN2	Digital control input for second half-bridge; complements IN1 to define bridge state per Table 1
17	Vref	Internal 13.5 V reference; decoupled with 0.22 µF capacitor to GND for noise immunity
18	GND	Additional ground pin - improves grounding integrity for sense and reference paths

Key Features

Feature	Design Value
Multipower-BCD Integration	Monolithic integration of isolated DMOS power transistors with CMOS/Bipolar logic eliminates need for external gate drivers
Cross-Conduction Protection	Hardware-enforced dead time >40 ns prevents simultaneous high-side/low-side conduction and rail-to-rail short circuits
TTL/CMOS/µC Compatibility	Logic inputs accept 0.3–0.8 V low and 2–7 V high thresholds - interoperable with 3.3 V and 5 V controllers without level shifters
Internal Thermal Shutdown	Auto-recovering 150 °C junction protection - maintains reliability during stall, overload, or poor heatsinking
Bootstrap Gate Drive	Dual BOOT1/BOOT2 pins support efficient high-side N-MOS driving up to 100 kHz without external charge pumps

Equivalent & Alternatives

The following parts are listed as comparable options for similar full-bridge motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
L6203	Higher RMS current rating (4 A), Multiwatt package, higher thermal resistance (R_{th j-amb} = 60 °C/W vs. L6202's 85 °C/W)	Suitable for higher-power 48 V motor systems requiring >1.5 A continuous current	Select L6203 when board space allows larger package and thermal budget exceeds 1.5 A RMS
TB6612FNG	Lower voltage (15 V max), dual H-bridge (2×1.2 A), no internal Vref, surface-mount only	Targeted at low-voltage robotics and portable devices; lacks bootstrap and sense reference	Choose TB6612FNG only for compact 3.3/5 V designs where 48 V operation and 1.5 A RMS are not required

Compared with L6203, E-L6202 offers lower thermal resistance in its Powerdip18 package for moderate-power 24 V systems, while differing from TB6612FNG by supporting higher voltage, integrated Vref, and bootstrap-based high-side drive - making it uniquely suited for industrial 24–48 V H-bridge implementations requiring robust current sensing and thermal resilience.

FAQ

What is the maximum continuous RMS current for E-L6202?

The E-L6202 is rated for 1.5 A RMS continuous current when mounted on a standard PCB with minimized copper area (T_amb = 70 °C). This value is validated per thermal data sheet Figure 23 and reflects safe operation without external heatsink under typical industrial ambient conditions.

Can E-L6202 drive 48 V motors without derating?

Yes - E-L6202 supports up to 48 V supply voltage (absolute max 52 V), but continuous operation at 48 V requires strict thermal management. At full 48 V, RMS current must be reduced to maintain T_j ≤ 150 °C, typically limiting sustained load to ~1.0 A RMS unless board-level heatsinking is enhanced.

Is an external bootstrap diode required for E-L6202?

No - E-L6202 integrates internal bootstrap diodes. Only external bootstrap capacitors (≥10 nF ceramic) are required on BOOT1 and BOOT2 pins. Adding external diodes is unnecessary and may interfere with internal charge-pump timing.

Does E-L6202 support current limiting without external ICs?

Not autonomously - E-L6202 provides the SENSE pin for current feedback but requires an external comparator or controller (e.g., L6506) to close the loop. The internal circuitry does not include programmable current limit or overcurrent latch functionality.
