Key Features
- Fixed-threshold single-channel reset IC covers 2.7 V to 5.5 V supply range, directly supervising 3.3 V and 5 V microcontroller rails
- No external components required—internal reference sets the reset threshold, minimizing BOM and PCB area in compact designs
- Active-low open-drain reset output remains asserted for a defined timeout after supply rises, ensuring stable processor startup
Applications
The TPS2013D is used in embedded microcontroller systems, industrial PLCs, and consumer electronics to guarantee a clean power-on reset and brownout recovery when supply voltage drops below a fixed threshold. It monitors the VCC rail of 5 V or 3.3 V microcontrollers and asserts a reset pulse long enough to prevent corrupted processor initialization. The 8-pin SOIC package fits easily alongside any MCU in space-constrained control boards and IoT sensor nodes.

Frequently Asked Questions
What supply voltage range does the TPS2013D monitor, and which microcontroller rails does that cover?
The TPS2013D monitors supply voltages from 2.7 V to 5.5 V, covering both 3.3 V and 5 V microcontroller rails in a single device. For a mixed-voltage board using a 5 V AVR alongside a 3.3 V ARM Cortex-M0, two TPS2013D ICs can supervise each rail independently using the same compact 8-pin SOIC footprint.
How does the TPS2013D's fixed threshold simplify design compared to adjustable-threshold supervisors?
Because the TPS2013D uses an internal fixed-voltage reference rather than an external resistor divider, the reset threshold is pre-characterized at the factory to match standard supply rails. This removes 2 resistors from the BOM, eliminates threshold drift caused by resistor tolerance (typically ±1%), and reduces design time for standard 3.3 V or 5 V processor reset circuits.
What happens to the TPS2013D reset output when the monitored supply experiences a brief 50 ms brownout dip below threshold?
When the supply drops below the fixed threshold—even briefly for 50 ms—the TPS2013D immediately asserts its active-low reset output and holds it low for the full internal timeout period (typically 100 ms to 200 ms after the supply recovers above threshold). This ensures the downstream microcontroller remains in reset long enough for its PLL and clock circuits to stabilize before resuming execution.
What is the pin count and package type of the TPS2013D, and how does that affect PCB placement near an MCU?
The TPS2013D is housed in an 8-pin SOIC (R-PDSO-G8) with a 1.27 mm pin pitch and a body measuring approximately 5 mm × 4 mm. The small footprint allows placement within 5 mm of the supervised MCU's VCC decoupling capacitors, minimizing trace inductance on the reset line and ensuring the supervisor sees accurate supply voltage without wiring-induced voltage drops.
For an industrial PLC card powered from a 5 V rail, when would the TPS2013D be chosen over a simple RC reset circuit?
A passive RC reset circuit cannot guarantee a minimum reset pulse width across temperature because capacitor leakage and resistor tolerance vary by ±20% over -40°C to +85°C. The TPS2013D internally specifies a minimum reset timeout of 100 ms regardless of temperature variation, ensuring the PLC's 16-bit processor always receives a valid reset duration before entering the main control loop—a requirement in IEC 61131-3 safety-aware PLC designs.
