s guide describes the characteristics, operation, and use of the TLV809K (TLV809KEVM-019),
TLV810S (TLV810SEVM-019), and TLV803S (TLV803SEVM-019) evaluation modules (EVM). The
TLV8xxxEVM is a fully assembled and tested platform for evaluating the performance of the TLV8xxx
family of supervisory circuits. The TLV809K, TLV810S, and TLV803S are single channel, 3-pin, 3.3-V
supply voltage supervisors (SVS) with built-in power-on reset generator with fixed delay time of 200ms.

Introduction
The TLV8xxxEVM helps designers evaluate the operation and performance of the TLV8xxx family of
single channel supervisors in a 3-pin SOT-23 package. This particular EVM configuration contains a single
SVS capable of supervising up to 6-V supply voltage. The TLV8xxx EVM is assembled with the TLV809K,
TLV810S, or TLV803S, all of which are 3.3-V supply voltage supervisors with threshold voltage, V
single channel supervisors in a 3-pin SOT-23 package. This particular EVM configuration contains a single
SVS capable of supervising up to 6-V supply voltage. The TLV8xxx EVM is assembled with the TLV809K,
TLV810S, or TLV803S, all of which are 3.3-V supply voltage supervisors with threshold voltage, V
IT
, of
2.93-V. To evaluate the TLV8xxx EVM with a different supply voltage, the IC will need to be replaced. The
TLV8xxx family of supervisory circuits provides initialization and timing supervision, primarily for DSPs and
processor-based systems; and, is available for supply voltages of 2.5-V, 3.0-V, 3.3-V, and 5.0-V.
