Obsolete Device TC52 Dual-Channel Voltage Detector Features Description • Two Independent Voltage Detectors in One Package • Highly Accurate: ±2% • Low Power Consumption: 2.0 μA, typical • Channel 1 Detect Voltage: 3.0V, 4.5V • Channel 2 Detect Voltage: 2.7V • Operating Voltage: 1.5V to 10.0V • Output Configuration: N-Channel Open-Drain • Space-Saving 5-Pin SOT-23 Package The TC52 consists of two independent low-power voltage detectors in a space-saving 5-pin SOT-23 package. Typical supply current consumption is only 2 μA at an input voltage of 2V. The voltage detection threshold settings are factory-programmed and guaranteed to ±2% accuracy. The TC52 is available with open drain (NMOS) configurations. Small-size, high-precision, low-supply current, and low installed cost makes the TC52 the ideal voltage detector for a wide variety of voltage monitoring applications.

TC52 2.0 PIN DESCRIPTIONS The descriptions of the pins are listed in Table 2-1. TABLE 2-1: PIN FUNCTION TABLE Pin No. (5-Pin SOT-23) Symbol 1 VOUT1 3.0 Description Detector #1 output Supply voltage input, detect voltage 1 2 VIN 3 GND Ground terminal 4 VIN2 Detect voltage 2 5 VOUT2 Detector #2 output DETAILED DESCRIPTION In normal steady-state operation and for either channel, when VIN > VDET-, the output is high, see Figure 3-1. (In the case of the TC52N, this is an opendrain condition.) If and when the input falls below VDET-, the output pulls down (Logic 0) to VSS. Generally, VOUT can pull down to within 0.5V of VSS at rated output current and input voltages. (Also see Section 1.0, Electrical Characteristics). VINx Detect Voltage VDET– The output, VOUT, stays valid until the input voltage falls below the minimum operating voltage, VINMIN, of 0.7V. Below this minimum operating voltage, the output is undefined. During power-up or anytime VIN has fallen below VINMIN, VOUT will remain undefined until VIN rises above VINMIN, at which time the output becomes valid. VOUT is maintained in its active low state while VINMIN < VIN < VDET+. (VDET+ = VDET- + VHYST). If and when the input rises above VDET+, the output will assume its inactive state (open-drain for TC52N).

DS20001430E-page 3 TC52 4.0 APPLICATION INFORMATION Pin 2 (VIN1) acts as both the input to Voltage Detector #1 and the power supply input for the chip. As such, always assign VIN1 to monitor voltages between 1.5V and 10V. Failure to do this will result in unreliable detector operation due to an out-of-tolerance supply voltage. In high-noise environments, it may be necessary to install a small input bypass capacitor (0.01 μF to 0.1 μF) from VIN1 to ground to minimize onchip power supply noise.
