Product details
Overview
MCP4013T-502E/CH from Microchip Technology is a volatile 6-bit digital potentiometer in SOT-23-6 package, configured as a potentiometer with 5 kΩ nominal resistance (±20%), 64-step resolution, and mid-scale power-on wiper default (0x1F). It operates from 1.8V to 5.5V, supports high-voltage tolerant U/D inputs up to 12.5V, and delivers 75 Ω typical wiper resistance for precision analog control in sensor biasing and gain adjustment circuits.
For engineers reviewing the MCP4013T-502E/CH datasheet, MCP4013T-502E/CH pinout, MCP4013T-502E/CH application, or MCP4013T-502E/CH equivalent, this page provides verified electrical specifications, SOT-23-6 terminal mapping, temperature-stable ratiometric tempco (10 ppm/°C), wiper settling time (1 µs @ 5 kΩ), and direct alternatives for voltage-controlled resistor replacement in industrial and automotive signal conditioning designs.
Technical Context
The MCP4013T-502E/CH implements a simple Up/Down (U/D) serial interface with CS enable, requiring no clock or address lines. Its internal 6-bit wiper register is volatile RAM, reset to 0x1F at power-up, and directly controls the resistive divider between terminals A and B via terminal W.
It supports both potentiometer mode (three-terminal use) and rheostat mode (two-terminal use by floating A or B), with resistor characteristics specified over 2.7V–5.5V while full device operation extends down to 1.8V. Absolute tempco is 50 ppm/°C (0°C to 70°C typ.), and ratiometric tempco is 10 ppm/°C - critical for stable voltage division across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Resistance | 5.0 kΩ ±20% - defines full-scale resistance between A and B terminals; enables precise gain/bias scaling in op-amp feedback networks. |
| Resolution | 64 taps (6-bit) - provides 15.625% step granularity; sufficient for coarse-to-mid precision trimming without excessive code density overhead. |
| Wiper Resistance | 75 Ω typical - minimizes insertion error in low-impedance paths; ensures <0.1% contribution to total resistance at mid-scale for 5 kΩ device. |
| Operating Voltage | 1.8V to 5.5V - supports single-supply operation from Li-ion battery (3.3V) to 5V logic rails; analog performance validated from 2.7V. |
| Ratiometric Tempco | 10 ppm/°C typical - guarantees stable voltage division ratio over temperature; essential for reference scaling and sensor excitation accuracy. |
| Wiper Settling Time | 1 µs (5 kΩ, CL = 100 pF) - enables rapid reconfiguration in closed-loop calibration or dynamic gain switching applications. |
| Supply Current | 1 µA max static - allows always-on biasing in ultra-low-power systems such as battery-powered IoT sensors. |
Pinout & Package
SOT-23-6 package with 1.6 mm × 2.8 mm footprint, 0.95 mm height, and standard gull-wing leads. Thermal resistance θJA = 120°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS) | Chip Select Input | Active-low enable for U/D interface; high-voltage tolerant up to 12.5V; internal weak pull-up/pull-down (16 kΩ). |
| 2 (VDD) | Positive Supply | 1.8V–5.5V digital/analog supply; powers logic and resistor array; decoupling recommended near pin. |
| 3 (VSS) | Ground | Reference for all analog and digital signals; must be low-impedance return path for wiper current. |
| 4 (U/D) | Up/Down Control Input | Edge-triggered direction control; high = increment wiper, low = decrement; 12.5V tolerant, VIH = 0.7×VDD. |
| 5 (W) | Wiper Terminal | Variable output node; connects to internal resistor ladder tap; 75 Ω typical series resistance affects signal integrity. |
| 6 (A) | Resistor Terminal A | Fixed end of resistor array; used with B and W to form potentiometer; floating enables rheostat configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Volatile 6-bit wiper register | RAM-based setting resets to 0x1F on power-up; eliminates nonvolatile write endurance concerns and simplifies initialization. |
| High-voltage tolerant digital inputs | CS and U/D accept up to 12.5V regardless of VDD - enables direct interfacing with 12V industrial control signals without level shifters. |
| Low wiper resistance | 75 Ω typical - reduces gain error in op-amp inverting configurations and maintains linearity under load currents up to 2.5 mA. |
| Extended temperature range | –40°C to +125°C operation - qualified for under-hood automotive and industrial motor control environments. |
| Simple 2-wire U/D interface | No clock, no address, no firmware overhead - reduces MCU GPIO count and firmware complexity versus I²C/SPI potentiometers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5160BRJZ-50-R7 | Nonvolatile EEPROM wiper memory; I²C interface; 5 kΩ, 64-step; 100 ppm/°C absolute tempco. | Requires I²C bus and firmware driver; retains setting after power loss - unsuitable where volatile reset is required. | Select when power-loss retention is mandatory and I²C infrastructure exists; avoid if GPIO-constrained or POR reset behavior is needed. |
| MCP4017T-502E/OT | Same family, SOT-23-5 package; rheostat-only configuration; no terminal B - pinout incompatible with MCP4013T-502E/CH. | Limited to two-terminal variable resistance; cannot configure as three-terminal potentiometer for voltage division. | Choose only for space-constrained rheostat use cases; requires PCB redesign due to missing B pin and different pinout. |
Compared with AD5160BRJZ-50-R7 and MCP4017T-502E/OT, the MCP4013T-502E/CH uniquely combines volatile mid-scale POR, SOT-23-6 potentiometer routing, and high-voltage U/D compatibility - making it optimal for cost-sensitive, GPIO-limited, and temperature-stable analog trimming where EEPROM wear or layout change is unacceptable.

FAQ
What is the power-on wiper position for MCP4013T-502E/CH?
The MCP4013T-502E/CH defaults to wiper code 0x1F (mid-scale, 31/63) at power-up. This is fixed behavior per the datasheet and cannot be altered in-circuit. The device uses volatile RAM, so all settings are lost on power removal and restored to 0x1F on next power cycle. No external programming or factory customization is required to achieve this behavior for the MCP4013T-502E/CH.
Can MCP4013T-502E/CH operate from a 1.8V supply?
Yes, the MCP4013T-502E/CH supports full device operation from 1.8V to 5.5V. However, resistor characteristics (RAB, linearity, tempco) are specified only from 2.7V to 5.5V. At 1.8V, wiper settling time increases and INL/DNL degrade - confirmed in DS20001978D Figures 2-7 and 2-10. For production designs requiring guaranteed analog performance, use ≥2.7V supply with the MCP4013T-502E/CH.
Is MCP4013T-502E/CH pin-compatible with other MCP401x variants?
No - MCP4013T-502E/CH (SOT-23-6) is not pin-compatible with MCP4011 (SOIC/MSOP/DFN), MCP4012 (SOT-23-6 rheostat), or MCP4014 (SOT-23-5). Only MCP4013 variants share the same SOT-23-6 pinout: CS/VDD/VSS/U/D/W/A. The presence of terminal B distinguishes MCP4013 from MCP4014, and its potentiometer configuration differs electrically from MCP4012's rheostat-only routing. Always verify pin mapping before substitution for MCP4013T-502E/CH.
What is the maximum current rating for the wiper terminal of MCP4013T-502E/CH?
The wiper terminal (W) of MCP4013T-502E/CH supports ±2.5 mA continuous current, as specified in Absolute Maximum Ratings. Exceeding this may cause irreversible resistance drift or thermal damage. At 5 kΩ and 5.5V, maximum theoretical current through RAB is ~1.1 mA - well within limit. For higher-current applications, use external buffering; the MCP4013T-502E/CH wiper is intended for signal-level control, not power handling.
Does MCP4013T-502E/CH support high-voltage U/D signaling independent of VDD?
Yes - the U/D input accepts voltages up to 12.5V regardless of VDD level, enabling direct connection to 5V, 12V, or mixed-voltage control buses without level-shifting circuitry. This is explicitly documented in Electrical Characteristics (VIHH = 8.5–12.5V) and High-Voltage Timing Waveforms (Figures 1-3/1-4). The feature is active for both increment and decrement, and timing parameters (tHUC, tHCUF) are defined specifically for HV operation of MCP4013T-502E/CH.
