APL6536 Four-Channel Supervisory IC Features General Description • 2.6V to 5.5V Input Voltage Range • Low Quiescent Current : less than 50µA • • High Accuracy Detection Threshold : ±1.6% Adjustable Undervoltage Lockout for Each Supply The APL6536 is a four channel supervisory IC designed to monitor voltage supplies in µP and digital system. This IC can supervise any positive voltage using an external resistor divider to translate to a lower voltage for comparison to the internal 0.633V reference. Once any VMON input falls below 0.633V the PGOOD output is pulled low, the hysteresis of the internal reference is 15mV. The PGOOD pin has an internal 20kΩ pull-up to VCC making an external pull-up resis- • Active high PGOOD Output • • Guaranteed PGOOD Valid to Falling VCC < 1V VMON Glitch Immunity : 30µs Lead Free Available (RoHS Compliant) • tor unnecessary. Each rail’s VMON point is independently adjustable with a resistor divider. The PGOOD output is guaranteed to be valid with IC bias lower than 1V. This IC is designed to reject fast line transient glitches 30µs on VMON input. The PGOOD output is an open-drain to allow ORing of multiple signals. If less than four voltages are being monitored, connect the unused VMON pins to VCC. The ENABLE input pin provides for a reset of the PGOOD output when it is pulled down below 0.5V. With an internal 10µA pull-up to VCC, it can be signaled with common logic or pulled to ground with a push button switch. APL6536 come in a miniature SOP-8 package.

This IC is suitable for both microprocessors or industrial system applications. Once biased to 2.6V and enabled the IC continuously monitors from one to four voltages independently through external resistor dividers comparing each VMON pin voltage to an internal 0.633V reference. The PGOOD output is an opendrain to allow ORing of the signals and interfacing to a wide range of logic levels. If less than four voltages are being monitored, connect the unused VMON pins to VCC. The PGOOD pin has an internal 20kΩ pull-up to V CC making an external pull-up resistor unnecessary. Falling Edge Glitch Filter Once any VMON input falls below 0.633V the PGOOD output is pulled low, the VMON inputs are designed to reject fast transients (30us). Enable The APL6536 has an active high enable function. Force EN high (>=0.5VCC) enables the PGOOD, EN low(<=0. 5V) disables the PGOOD and enter the shutdown mode and it also causes the PGOOD to discharge through a 1MΩ resistance to ground. In shutdown mode, the quiescent current can reduce below 60uA. With an internal 10uA pull-up to VCC, it can be signaled with common logic or pulled to ground with a push button switch.
