Product details

Overview

TSOP58238 from Vishay Semiconductors is a 38 kHz infrared (IR) receiver module optimized for long-burst remote control systems, featuring AGC4 configuration for enhanced noise immunity against fluorescent lamps, Wi-Fi, and LCD TV interference. It integrates a PIN photodiode and preamplifier in a leaded Minicast epoxy package with built-in IR filter, operates from 2.0–5.5 V, draws ≤0.45 mA supply current, and delivers active-low demodulated output directly compatible with microcontrollers.

For engineers reviewing the TSOP58238 datasheet, TSOP58238 pinout, TSOP58238 application, or TSOP58238 equivalent, this device is selected for NEC, RC5, RC6, Sharp, and Sejin 4PPM protocols in consumer remote control designs where ambient light rejection, burst-length tolerance (>10 cycles), and stable sensitivity down to 0.3 mW/m² are critical.

Technical Context

The TSOP58238 implements a band-pass filter centered at 38 kHz with ±5% frequency tolerance and AGC4 gain control, enabling reliable detection of long-burst IR signals while suppressing continuous or modulated ambient interference. Its internal control circuit enforces strict burst timing constraints: minimum gap time ≥10 cycles and >3× burst length for extended data streams.

It features optical directivity of ±45° half-angle, spectral peak sensitivity at 950 nm, and maintains functional operation across –25°C to +85°C ambient temperature. Output pulse width conforms to tpi ± 4/f₀ (f₀ = 38 kHz), ensuring compatibility with standard IR protocol timing envelopes.

Key Specifications

Parameter	Value and Actual Design Meaning
Carrier frequency	38 kHz - precisely matched to NEC, Sharp, and Sejin 4PPM remote protocols
Supply voltage range	2.0 V to 5.5 V - supports direct interface with 3.3 V and 5 V microcontrollers without level shifting
Supply current (typ.)	0.35 mA at 3.3 V - enables low-power remote receiver designs with battery life extension
Minimum irradiance (NEC)	0.3 mW/m² - ensures reliable reception under typical indoor lighting conditions
Output logic polarity	Active-low - simplifies MCU GPIO interrupt handling with falling-edge triggering
Transmission distance	18 m with TSAL6200 emitter at 50 mA - meets consumer remote range requirements
Operating temperature	–25°C to +85°C - suitable for indoor consumer electronics without thermal derating

Pinout & Package

TSOP58238 uses a 3-pin Minicast through-hole package (5.0 mm × 6.95 mm × 4.8 mm) with leaded mounting and integrated IR-filtering epoxy encapsulation.

Pin/Terminal	Circuit Role	Design Meaning
1	OUT	Demodulated active-low output signal - directly drives MCU GPIO or interrupt pin
2	GND	Analog ground reference - must be connected to system ground with low-impedance path
3	VS	Positive supply input - requires local 100 nF ceramic decoupling capacitor per datasheet recommendation

Key Features

Feature	Design Value
AGC4 configuration	Optimized for long-burst codes (e.g., NEC, RC6) with superior suppression of fluorescent lamp noise patterns shown in Fig. 14/15
Integrated IR filter	Blocks visible and near-IR ambient light outside 850–1050 nm band, reducing false triggers from sunlight or incandescent sources
Burst timing compliance	Enforces ≥10-cycle minimum burst and >3× burst-length gap timing - ensures robust decoding of RC5/RC6 frame structures
DC supply ripple immunity	Maintains sensitivity up to 30 kHz AC disturbance on VS (Fig. 7), eliminating need for ultra-clean LDO in cost-sensitive remotes
Horizontal directivity	±45° half-angle (Fig. 11) - provides wide-angle user coverage while rejecting off-axis interference sources

Equivalent & Alternatives

The following parts are listed as comparable options for similar IR receiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSOP58438	Same AGC4 configuration and 38 kHz center frequency, but rated for higher maximum envelope duty cycle in long-burst mode	Preferred for RC6 and r-step protocols requiring >72-cycle burst gaps; slightly higher cost	Select TSOP58438 when designing for RC6-compliant systems needing extended burst tolerance
TSOP38238	Legacy 38 kHz receiver with AGC2, lower noise immunity, no explicit support for RC6 or Sejin 4PPM in datasheet	Limited to basic NEC/Sony protocols; lacks suppression for complex fluorescent lamp modulation (Fig. 15)	Choose TSOP38238 only for cost-sensitive legacy NEC-only remotes without Wi-Fi or modern display interference

Compared with TSOP58238, TSOP58438 offers improved burst-gap handling for RC6, while TSOP38238 sacrifices noise immunity and protocol breadth for lower unit cost - making TSOP58238 the balanced choice for multi-protocol, interference-prone environments.

FAQ

What is the carrier frequency and AGC setting of the TSOP58238?

The TSOP58238 is configured for 38 kHz carrier frequency with AGC4 gain control. This setting optimizes noise suppression for long-burst protocols like NEC and RC6 while maintaining compatibility with Sharp and Sejin 4PPM codes. AGC4 provides stronger rejection of fluorescent lamp and Wi-Fi interference compared to lower AGC variants, as confirmed in the Vishay datasheet section "SUITABLE DATA FORMAT" and Fig. 6–7.

Does the TSOP58238 require external components for basic operation?

Yes - the TSOP58238 requires a 100 nF ceramic decoupling capacitor between VS (pin 3) and GND (pin 2), as specified in the Application Circuit diagram (page 2). No pull-up or series resistor is needed on the OUT (pin 1) line due to its active-low open-collector-like output stage, which interfaces directly with 3.3 V or 5 V MCU GPIO pins.

Is the TSOP58238 qualified for automotive applications?

No - the TSOP58238 is explicitly stated in the Vishay datasheet to "have not been qualified to automotive specifications." Its operating temperature range is –25°C to +85°C and it lacks AEC-Q200 stress testing or automotive-grade qualification. It is intended solely for consumer and industrial indoor remote control use.

What is the minimum detectable irradiance for NEC code with the TSOP58238?

The TSOP58238 has a minimum irradiance threshold of 0.3 mW/m² for NEC code, as specified in the "ELECTRICAL AND OPTICAL CHARACTERISTICS" table (page 3). This value is measured under dark ambient conditions with Tamb = 25°C and confirms reliable reception at typical indoor distances using standard IR emitters like TSAL6200.

How does the TSOP58238 handle ambient light interference from fluorescent lamps?

The TSOP58238 suppresses both mild and complex fluorescent lamp IR disturbances - including those shown in Fig. 14 (low-modulation) and Fig. 15 (high-modulation) of the datasheet - via its AGC4-controlled band-pass architecture and burst-length validation logic. This ensures no spurious output pulses occur during lamp flicker, unlike lower-AGC receivers such as TSOP38238.
